Last had my periods on June 16th, had sex on July 6th & 13th, but am not seeing my period. Could I be pregnant?
Hi Edith, those dates wouldn’t have fallen in your fertile period. I would recommend a pregnancy test but if it’s negative and you still don’t see your period, give your doctor a call.
Good afternoon please I saw my period on the 26th of June so I had an unprotected sex with my finance on the 7th of July so since then i have been feeling symptoms of pregnancy like body temperature early morning, sharp pain under my abdomen, always hungry each time i wake up in the morning, always eating and eating, my eyes keep turning me…now i have been bleeding since yesterday being 18th of July so i checked my self with test strip and it showed negative… Please my question now is why was i feeling those symptoms if i wasn’t pregnant what could be the problem? Thanks
Hi Grace, there might not be a problem. It could be that you wanted to get pregnant and you are excited and your mind tricks you into thinking that you are pregnant, noticing things that you might not have noticed because you were looking for them. This is just a suggesting but that could be regular PMS symptoms.
Hello I stopped my birth control pills on June 22nd had unprotected sex until the 25th when I started bleeding until the 29th been having unprotected sex since then no cycle since the 29th been nauseated, cramping, headaches and bloated is it to early to test?
Hi Jamie, I would wake to test until you actually miss your period. You don’t want to be disappointed when in fact the test might not detect the hormones yet.
Saw my period on the first of July 2019. Made love to my bf on the 13th. Am I in the fertile window?
Hi Goli, yes you would have been right in the middle of your fertile period, which based on the calculator would have been from the 11th to the 15th. Good luck!
i had my last period on the 27 of may up till now i have not seen my cycle
Hi Mary, take a pregnancy test. If it’s negative then maybe you’ll want to call you doctor and get some tests done.
Hey I had sex June 30th & July 7 my last period was June 14th and I’m having pregnancy symptoms like tender breast and my temperature is changing like my body gets hot at night but June 11th I started bleeding .
Hi Kayla, most likely PMS symptoms. When we want to be pregnant we can pretty much feel like we are having symptoms of pregnancy even when we aren’t. That was most likely your period on the 11th, and if you want to verify that you can take a pregnancy test.
My last period was 11 June, I have 28 days cycle and I had sex with my boyfriend on 3 July. took postinor2 the next day and was to have my periods on 9 July. its 4 days now I haven’t seen my period. Am I pregnant???
Hi Claudia, a lot of time emergency contraception will affect the next cycle, having it come either sooner or later than it normally would. You are adding hormones in your body to try and prevent a pregnancy. I would recommend still taking a pregnancy test but also considering that your period might just be late because of the pill.
I saw my period on 15 of June 2019, now I saw it on July 10, 2019. Is it normal?
Hi Blessing, yes this seems normal.
I had my period on 3rd of June, I had unprotected sex with my husband on the 9th 11th 13th and 14th, had spotting on the 15th of June and also had another spotting in the 27th of June….my period was supposed to come on the 28th of June. It’s 11th July and my period is yet to start… I’ve Been having cramps and nausea for weeks now.. Could I be pregnant cause I’ve been trying to conceive since January…
Hi Linda, you could be. You had intercourse during your most fertile days. I would take a pregnancy test.
please, I usually see my period every 28 days but when i have my first sex I later see my period as 25 days. So the following month it reduced to 20 days. Now the following month I have not seen my period and. It’s almost 28 days now I haven’t seen it now.
Hi, if you haven’t seen it yet and it’s almost 28 days it could be that your period is getting back into its normal rhythm for you. I would wait until after your period would be anticipated within that 28 days and if nothing then maybe a trip to your doctor is necessary to determine if there is anything else that is going on.
I saw my period on June 5th and I haven’t seen my period yet does it mean I am pregnant?
Hi Queen, you could be if you had sex during your fertile period. Take a pregnancy test.
Hi my name is Maite. I was on my period June 14 my last day. Then we had unprotected sex June 19 2019 and again on June 27 2019 we had sex twice that day unprotected. Then I got my period on July 8 may I possibly be pregnant?
Hi Maite, if you got your period then you most likely would not be pregnant.
I saw my period may 22 to 25 and now am seeing it June 16 to 19. please with this date am I safe? Only day one has heavy flow.
Hi, you most likely are. Sometimes our periods become shorter or longer because of our lifestyles and changes and stress. Sounds normal.
My period was on June 11 then on July 4 , when is my next period ?
Hi Sophia, should have been July 9th.
I had my menstruation last May 26 until June 2. I was late last month because I had allergies and I need to drink antihistamine for it so I was late for 10 days (my period should have started last May 15). I had sex last June 13 (which is protected) and also last June 20 (unprotected but it was withdrawal). It is now July 07 and I still don’t have my period. I don’t have symptoms and I took pregnancy tests twice but both are negative. I am thinking that if I am pregnant right now it should have been a positive. Am I pregnant or I’m just stressed?
Hi Angel, it could be that your periods are late due to your bodies reaction to the antihistamines and your allergies. It’s quite normal if you are late. And yes if you are still late in a week or so take another pregnancy test. If you are pregnant the test should show it. If you have concerns or don’t get your period make an appointment with your doctor.
So me and my man hag sex all through May. Well Mary 27 I got arrested and spent almost a month in jail I got out on May 27th but while I was in jail I had a incident with a little bit of spotting and I was waiting on my period. But it never came instead I got a couple days of spotting and then it went away again and then about a week later I got a little bit more spotting. I am waiting on my period. Now which I should be getting any day but I’ve also been experiencing very sore boobs nausea the tiredness the dizziness my hormones in my feelings have been through the roof I seriously I’ve been so in my feelings and so not cool and everybody keeps saying I have a glow to me I took a dollar pregnancy test and it came back negative so I threw it away and when I went to throw the trash later on I am 50 bucket in the test fell out and now that it’s all dried up you could see what the outlining of the second positive line where it would be. When is the best time to take a pregnancy test?
Hi Tasha, the additional line one the pregnancy test after waiting and letting it dry could just be evaporation lines. However, if you haven’t gotten your actual period I would take another pregnancy test, especially if you are late with what is generally considered your period. At any point in time after implantation if you take a pregnancy test you should know if you are pregnant or not. Good luck.
