Hi, I got married in October 2015, I’ve had unprotected sex until now, but my menses haven’t been delayed since then, it always comes at the expected date. Please what does that mean? I really want to get pregnant.
Hi my last day of my period was March 17 I had unprotected sex the same night is it a higher rate of getting pregnant?
No it is not. If you have a regular cycle, the chances of getting pregnant would be low.
I usually have a 7 day cycle but this time I only had a 3 day cycle…. That why I just wanna make sure if there was a chance or not.!!
I saw my menses on the 5th of March 2016 and now I’m seeing it again on the 31st of March 2016. Is it normal?
Some women do have this experience. You need to check with your doctor. Please read this article for more information http://womanjunction.com/menstrual-cycles-month/
My last period were 21-25 March, when am I fertile to conceive?
Ovulation typically occurs 14 days before the start of your menstrual period. If your cycle lasts for 28 days, you can ovulate on the 14th day like the average female. You’re likely to ovulate from April 02 to 06, 2016 if you have a regular 28 days cycle.
My last period was Feb 26th and still nothing. Today I had lower back aches not pain and very light spotting maybe twice today.. I’m usually pretty regular but I’m thinking im just late… No sore breast. Do have headaches feel nauseous at times. What do yall think?
Hello D’Ann, there might be many reasons for late period. But, they include pregnancy as well and no sore breast does not mean that you cannot be pregnant. What is the usual number of days in your cycle?
Hi,pls my last menses started on the 28th February and ended on 3rd March. on the 4th March l had sex with my current boyfriend and on the 7th march l had sex with my ex-boyfriend who came to visit me without my current boyfriend knowing and also without taken any drug. On the 20th march l had sex with my current boyfriend which after l took postinor 2. My menses was to come on the 24th but didn’t come and now the pregnancy test shows I’m pregnant but doesn’t know whose is responsible whether its my current boyfriend or ex-boyfriend?please explain for me and the one responsible
Hi Jamy, there is no way to determine this other than a DNA test. With this info., more chances are that your ex may be responsible as 7th March must be closer to your ovulation time. BUT, I repeat that without a DNA test, it’s impossible to know for sure.
Hi. My period was on the 7th of March 2016 and ended on the 10th of March 2016. I had unprotected sex with my husband on the 12th to the 20th of March 2016. I have a cycle of 26 days. Am I pregnant? It’s now 4 days to my next period.
You were fertile from March 17 to 21, so it’s possible that you conceived. Good luck!
Had my period March 8th…took pregnancy test 3/29/16. I am pregnant ????
Congratulations!
I gave birth 5 months ago. After one month of delivery, I saw my menstruation the next month. But since this year, I saw it on the 20th of December, then 22nd of January and the 25th of February but I have not seen it this March. I’m confused about how to calculate my cycle and I menstruate for 5 days. Please help me.
The menstrual cycle starts on day one of the bleeding in one month to day one of the bleeding in the month that follows. So if you have a period on December 20 and another on January 22 – there would be 33 days between those dates. Count December 20 as day 1, continue counting until you get to January 21 – you will count 33 days. January 22 would be day one for the next cycle. The days between your January and February cycles would be 34 days.Read this article http://womanjunction.com/menstrual-cycle-calculating-manually/ for more information.
I saw my period on the 1st and the 27th of March. Please, when will I be fertile?
If you have regular periods then you’re likely to ovulate on April 8 to 11.
Ive had sex a couple times right after my period ended , im expecting my period to come on the 26th of March which has past , im 4 days late to my periods due date . Lately ive been feeling sick , feeling nausea and having headaces !

Hi Savannah, I would suggest that you see a professional for this. All the best!
Hi, my last period was March 9th. I had sex with my husband from the 14th of March to the 26th. My period time is 30 days once. Now I feel dizzy and vomiting then stomach pain. I think this time I am getting pregnant. Is my thinking correct or not? I don’t know. Pls tell me are these pregnancy symptoms or not?
You were fertile from March 23 to 27, 2016. Your next menstrual period is expected to start on April 08, 2016. Wait to see if your period will arrive at that time.
my name is Martha, I saw my period on the 2nd of march and had unprotected sex with hubby, my period is late by 2 day, but the test slip is showing negative, is it too early to test?
Hey, I normally feel my ovulation but this month I didn’t. My first date of my last period was March 5 and per the calculation I should have ovulated March 17-24. I had protected sex on the 20th… I’m worried because I normally feel my ovulation and sitting here thinking…I didn’t for this month. The calculation states my next period is April 2nd should I just wait to assume?
Yes, you should.
Hey, I had my period on the 22nd of feb and my menstrual cycle is 28days. My period is late, I had a pregnancy test a few days ago which was negative but I also have period symptoms; break out, cramps, tender breasts.
Hi. I am Sweety, my last period started on 23 March. What is the best time to get pregnant? My cycle is 28 days.
The best time to get pregnant is April 04 to 08. Good luck!
