My last period was on november 26th and I get my period about every 30-32 days. I had sex earlier in december sumtime between the 6th-10th, but I wasnt ovulating and we tried for the 2 months b4 that on the day I was ovulating but nuthing happened. Then on dec. 16 I had sex with a different person. I was supposed to get my period around the 29th of december and never did, I took a test on the 30th and it came up positive... What day was I most likely to conceive?
