Hi just a quick question my last period was november 30th its now jan 5th still no period i tested negative should i still wait to retest
Hello, Yes wait couple days and test again because you can still be pregnant even with a negative test if it turns out negative again visit a doctor.
I had my period on November 12, 2015 and got a positive ovulation on December 6, 2015. I have PCOS so my periods are very unpredictable. I have taken several HP tests and the first was very faint and the last 3 were positive. Any idea how many weeks pregnant I may be? I am waiting on getting a doctors appt but was just curious on the possible due date.
My most fertile period is Dec 28, 2015 to 1 Jan 2016. I had unprotected sex on the 2nd of Dec. Will I get pregnant?
The chances of being pregnant would be very low.
Hi I had sex on the 24th of December 2015 and my period started on the 14th of December 2015 but the sex was unprotected. But I took a contraceptive pill clear 72 after 5 hours of having sex. Is there any chance of being pregnant? When will my period come again if I’m not pregnant? My period cycle is 24 days.
The chances of you being pregnant were high since you were fertile from December 22, 2016 to December 26
Your next menstrual period is expected to start on or around January 07, 2017 if you’re not pregnant.

Hi, Yes it is possible you are pregnant take a pregnancy test to find out.

Hi,Hello, Well you saw your period on the 17th of june if it was actually your period and not some other bleeding associated with pregnancy then it would be anytime after your period when you had unprotected sex again.
I saw my period last on 9th of December and I had an unprotected sex on the 30 of December I’m expecting that of January it hasn’t come and I have been having pains on my nipple and a little drop of blood like dark brown for 2 days now. Am I pregnant?
Hi, You could be pregnant take a pregnancy test to confirm.
Hi, Its possible you are pregnant as you had unprotected sex take a pregnancy test to find out.
I had my period on october 21 2015 on Nov 06 2015 I had protected sex. By Nov 12 2015 I was very ill throwing up non stop and on Nov 19 received a positive pregnancy test. On Dec 17 2015 I had an Trans V ultrasound.the CRL measurement was 4.30 cm and 4.36 cm which would put my dates off by LMP. I have looked up charts to see where these measurements put me which is about 11 weeks 2 days but I should have been 7 weeks 6days. Then the doctor said he was concerned if I was correct with my dates because the measurements were off and stated I was 9 weeks 1 day. I did not receive an EDD because this was a sick visit not first OB that is not scheduled until Jan 11 because of my dates I gave to establish care. I am very confused what to believe and need help. Does this make sense to you? What condition or defects could this mean?
Thanks in advance
