I had last period oct 31 had sex nov 17 I have not started my period.. What should I be thinking?
Your thoughts will vary depending on the number of days in your cycle. If you have a 28 days cycle then it is possible that you were fertile on November 17 and could have conceived.
I had my period on the 20th of November and it lasted for five days. I had sex many times after that and the last date being on the 30th November, I have been on the pill for the past few months and stopped during the second week in November. Is it possible to get pregnant right after stopping the pill?
I had periods on Nov 4 it completed on Nov 8. I had sex with my boyfriend on Nov 28 without precaution. Is there any possibility to get pregnant?
Your chances of being pregnant depend on whether you were fertile on or around the date that you had sex. It is important to know the number of days in your menstrual cycle and whether you have regular or irregular periods. If you have a 28 days cycle you would have ovulated on November 16 to 20, 2015; November 28 is outside of your fertile window so you may not have conceived.
Hi, i menstruated on the 1st of October and again on the 30th to 1st November, i was expecting to bleed in November but i didn’t, is that normal?
Hi my periods are on time usually from the 10th to the 13th and I had unprotected sex the 27th with my husband and we are trying to conceive I’m just wondering can we be pregnant because I’m not feeling my normal premenstrual symptoms?
Hello, Well if you had unprotected sex you could be pregnant if not there are other reasons why this may be happening for example:Cramping may be a symptom that ovulation is taking place. Sometimes the menstrual cycle is delayed, and instead of menstruation, ovulation is still taking place, giving rise to cramps but no period,Endometriosis,Stress or even Perimenopause

You would have ovulated from November 09, to 13, 2015. In December, you would be ovulating from our December 03 to 07, 2015. Your next cycle would begin on December 19, 2015.
Hey. I was wondering I had my last period on the 24th of October and now it’s the 30th of November. Is there a possibility that I can be pregnant? And I did have unprotected sex.
If you had unprotected sex then you are at a high risk of becoming pregnant. You can now take a pregnancy test to confirm your status. You can get the most accurate result if you wait at least one week after missing your period. In addition, the result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time. The urine-based home pregnancy tests offer great accuracy.
