Hi my girl had her period on 28 may and finished on 01 June. We had sex between 6 June and between 14- 17 June she took emergency pill and then the morning after and started taking birth control pills. Until today 3 July no period, has the combination contributed or….? Advise christo
Hi Christo, Well first lets start with the emergency contraception. If she took it after 72 hours after intercourse then it most likely would not be effective. Even at 72 hours the effectiveness decreases the longer you wait. The combination of the hormones could result in her period being delayed, however we are now past 30 days. I would recommend a pregnancy test for your significant other.
Good evening, I need some quick answers to why I’m having all the pregnancy symptoms before my period is due. Doctor did blood work and a sonogram and said it’s all negative this is most certainly not my first baby or pregnancy what is going on. And I did everything correctly as far as tracking my cycles to get pregnant I’m so lost. My period is due July 6/7 2019 please help
HI Shanell, could just be PMS honestly. If everything is negative then you shouldn’t be worried, but if you don’t get your period then you should take a pregnancy test again, honestly though it sounds like you aren’t pregnant and you are just experiencing more significant PMS symptoms.
I saw my period may 22 and June 19. My cycle is usually 28 or 29 days cycle. When am I supposed to ovulate? Now I met my husband on 23, 24, 25, and then the 30th and 1st july. Is it possible to be pregnant
Hi Precious, You would have been going through your fertile period from June 29th to July 3rd so yes it’s quite possible that you could get pregnant. Your ext period is due around the 17th of July so if you miss it test then. Good luck!
I’m suppose to have my menses on the 24th of June buh has sex from 22nd -26th June and yet still I’ve not had my period…. Is it possible to get pregnant?
Hi Debby, at that time you would not have conceived. It would have been too close to your period that you would have already been out of the fertile period. However, that it based on a 28 day cycle which is average. Did you have sex at other times during your cycle, drastic weight changes, illness, medications, stress, etc? If so that could be the reason and therefore I would take a pregnancy test, especially if the first one is the case.
I did my period on June 6 and have sex June 19 can I be pregnant
Hi there. You could be. Your fertile period would have been from the 16th through the 20th, so if you had unprotected sex during that time frame you could get pregnant. I would wait until your period and if it’s late take a test. Good luck!
I just lost a baby on the 4th and finally stopped bleeding around 20- 23 and me and my partner had sex on the 24th of June and I started bleeding on the 26th out of no where what could it be ?
Hi Lizzy, could be your period honestly (especially if you aren’t nursing even though that isn’t a reliable form of birth control). It could also be that your body wasn’t completely healed and sex irritated already irritated areas (if you had a vaginal birth). If you aren’t trying to get pregnant again so soon I would make sure that you are using some sort of protection. Again, it could be your period.
According to the calculator am supposed to menstruate on 27 July but I been ovulating for two weeks now. What is happening to me?
Hi Christa, why do you say that you have been ovulating for two weeks? What are the symptoms of that because if you are supposed to have your period on July 27th, you are almost a month prior to that which could be your period now. Your comment is a bit confusing so I’m having trouble helping you.
I had my period on 3rd June and had sex on the 14th June…so on the 27th I started experiencing my period but it seems thick like clot…I’m confused…please help me out ….am Rita
Hi Rita, it could be your period and just heavier than usual. That can happen as our cycles can change. As for blood clots while for some women that is normal with a heavy period, for some it signifies and early miscarriage where you don’t even know that you are pregnant. If your period continues to be normal after that just consider it done and next month see what it’s like.
Hi i saw my period on 8th June and it still come on 28th June is it normal?And what is the date of my fertile
Hi Mariam, your fertile period for June would have been the 18th to the 22nd based on a 28 day cycle. While it’s normal for your period to sometimes change due to our life happenings, sometimes it’s a little worrisome. Consider this your period and watch for next month unless you are having other symptoms that may warrant a visit to the doctor.
Hi my name is Eric. My GF period starts on June 16 and ends June 19, so please what’s the right time for me to shoot on target and if I miss it this time what would be the appropriate time in her next period? 28 days cycle
Hi Eric, that would have been from June 26th through the 30th. Her next period would be anticipated around July 14th, and your best time to try and get pregnant in July would be to have sex between the 24th and the 28th of July. Good luck!
I had gotten my perod may 27th 2019 so I thought I would get my period on the 24th of June but it’s the 26th now. Am I pregnant or am I just overthinking this. Thank you
Hi Courtney, you could have been overthinking things. Have you gotten your period? If not take a pregnancy test.
I saw my period 9th of June, when are my most fertile to get pregnant For a baby boy
Hi Esther, you can try in July from the 17th to the 21st approximately depending on when you got your period for July. Ideally as they say try at the beginning of your fertile period for the best chance to get pregnant.
hi,I had my menses 28 of may and I finished June 1, when am I suppose to see my next menses. I am worried I thought I should have my next menses by 24 of June until now I have not seen anything, is there anything to be worried about.
Hi there, it could have been normal that you didn’t see your period on the 25th. It could vary a few days. If you haven’t seen it yet, take a pregnancy test.
Hey…I had my period on the 1st of June till the 4th of June…so when did I ovulate and I had sex on the 21-23 of June… When is my next period and can I be pregnant?
Hi Lee, based on the calculator your fertile period was from the 11th to the 15th which means that you most likely wouldn’t get pregnant this cycle. With your next period expected to start (based on a 28 day cycle) the 29th of June, your next fertile period would be from the 9th through the 13th. This would be the ideal time to have sex to try and get pregnant.
my friend last period is May 28 and it ends of June 2 and now June 24 she got spotting is there something to worry about it?
Hi Jessa, most likely its her next period starting unless she could be pregnant then it could be implantation spotting. But otherwise, nothing to worry about.
Everything just seems so confusing to me. I know for a fact I ovulated June 22nd 2019, because I had all the ovulation symptoms and I had unprotected sex June 21st 2019. So did I conceive on the 22nd or the 23rd and my last period was June 9th
Hi Shanell, your calculations seem to be correct based on the calculator so I would definitely wait until your next scheduled period (roughly around July 7th based on a 28 day cycle), and if you are late take a pregnancy test. Good Luck!
