I had Mirena removed November 3rd. My cycle came November 7th and lasted 7 days which is normal. I had my cycle December 6th and ended the 8th. I had another cycle December 30th and ended January 1st. I haven’t had a cycle for January yet unless the second cycle was my cycle for January. Could I be pregnant?
I had my last period December 13th lasting six days. Being unprotected everyday after that using the withdrawl method, which is not a good strategy, I know. I have irregular cycles and my period has not come yet. Im not sure if I should take a pregnancy test, I am scared…
Go ahead and test now. Good luck!
Hi. the first day of my last period was on the 14th of Dec. and the last day was on the 17th. I had unprotected sex on the 18, 22, 25, 27, and the 31st. I have a 32 day cycle and I was supposed to get my period on the 15th of January and I have this feeling in my lower abdomen it feels like it’s something poking…but I have no pregnancy symptoms at all.
my boyfriend and I were having sex and the condom broke. Lately, I have been having back pains..it is the lowest part of my back by my butt. I also have pain in my left side and the bottom of my stomach. what is going on? My period came on Dec 26. I have about 33 or 34 day cycle.
I had my period on the 16th Dec 2016, not had my period of January 2016, in November I had my period on the 10th, and December the date changed, will I get my period on the 22nd of January, because I counted from Nov to Dec 37 days?
My period came on December 8th went off December 12th I have a 32 day cycle when do I ovulate? Me and my husband are trying to get pregnant but don’t know when to have sex when I’m fertile the most
Hello,Your next most fertile period would have been December 24, 2015 to December 28, 2015.
If your cycles are 32 days long, you ovulate on day 18.
My last menses started on 2nd January and ended on 5th January 2016. I have a 29-day cycle, I’ve been having unprotected sex with my boyfriend from 15th Jan up until my fertilization last. We both want a baby. How soon can I take a pregnancy test?
Hello,Wait at least 2 more weeks i know the wait is horrible but you want to get accurate result good luck 🙂
My last period was December 12 I had unprotected sex December 27, am 10 days late for my period am I pregnant?
My period reduce from five days to three days and doesn’t flow as usual though is still very regular but have been trying to conceive for 8 months. my question is can that affect me getting pregnant?
Hi, No i don’t think that affects your fertility lots of women experience longer or shorter periods sometimes,all you need to do is calculate you ovulation days properly so you don’t miss having sex before you ovulate.
I had my mirena taken out on the 24 of December, had sex that same day …then had my period again for 1 day on the 6 of January now is the 18 of January and i feel cramps and nausea …i would like to know when is my next period coming or am i pregnant???
Hi,If what you experienced on the 6th of January was actually your period and not some other kind of bleeding associated with pregnancy like…implantation bleeding.then you might not be pregnant the only thing you can do now is wait and take a pregnancy test to find out.
hi my last month periods was 25th December, now 18th Jan again. it comes too early…in last month after my period continuously till jan 8th we had intercourse. don’t know what’s happening in my body. often i get too early periods …this all is happening only after marriage …some physician said I have bilateral small cysts in my ovaries. is that a reason for my delaying pregnancy?
pls I had my menses from 29th december to 1st january. I calculated with the menstrual calculator and my ovulation was from the 10-14 January 2016. please does it mean 18 january is a safe day for me? tnx
the chance of conception is lower if the calculation is correct, but you should still use some form of contraception if you don’t want to get pregnant
Hi I just gave birth 3months ago and had my first menstrual period on December 17,2015. My husband and I make love January 1st,2016 and it was withdrawal method. It’s already January 18 and still I have no period. I am confused in counting my cycle what is suppose my next menstrual period my period ended December 25,2015. Is it possible I am pregnant again? Thank you and God bless you
Hello,Since it was unprotected sex and the withdrawal method doesn’t work sometimes it is possible you are pregnant,all you can do now is wait and take a pregnancy test.
My period was on 4th of this month but I didn’t get it. On the 9th of this month, I had sex where I was wearing a panties but still I am scared of being pregnant. I took a pregnancy test after 2 days and it showed negative. I took after a week like on 17th Jan and it was negative but I am not getting periods. Why?
You missed your January period but had unprotected sex in that month as well so testing in January may not give you the most accurate results. Your period may be late for other reasons but wait to see if your February period will come. If it doesn’t come then take the test one week after that February date.
I saw my period on 25 December 2015, had unprotected sex on January 4,5,7,8 2016. Now I am feeling sick. could it be that I am pregnant?
Your chances of being pregnant depend on whether you were fertile on or around the date that you had sex. Can you confirm the number of days in your menstrual cycle? This information is needed to provide you with the most accurate response.
Has your boob started swelling a little bit yet
Yes
My last period was the 12th of Dec. I took a test yesterday it was negative. I have an irregular cycle and my period lasted 7 days. I have had unprotected sex on Dec 30. I’m fatigued, dizzy, have huge boobs, back pain, frequently urinating and I’m always wet below thinking it’s my period but it’s not diarrhea. Nausea you name it…I already have five kids and I don’t know what’s wrong with me, could I be pregnant?
The best way t confirm is to ensure that you take the test at the right time. If you miss your January period, then take a pregnancy test at least one week after that date.
Ok then that’ll be the 19… let’s see what happens. Thank you.
Still nothing 36 days since last period. Now I’m going to the rest room every hour can’t control bladder. 3 negative test and I got clear liquid coming from boobs. Im l mean my boobs are huge and nipples,very sensitive…. what now I’m still lost
