I am 29 years old, had sexual intercourse on the 4th day of my menstrual cycle (being the first bleeding day the March 14 morning). I had sexual intercourse on March 17th, no ejaculation inside though. The period lasted around 7 days with light spotting. I thought I started ovulating from March 27 to April 11, since I had recurrent cervical mucus changes.
My usual cycles are 28 - 30 days from each other.
Today is the 39 so far my longest cycle.
I had a lot of stress the weeks I was supposed to be ovulating, and since my last period I lost around 5 pounds, because I got braces and my diet changed a lot.
Last week I started to have PMS-like symptoms, sharp pains on the side of my breast, small cramps and a bit of breast enlargement. The usual that I always have before any menstruation cycle.
I am usually regular at my cycles and I hardly believe that I could changed from regular to irregular less than a month.
What are my chances to have ovulated during my 4th day of menstruation, or my chances of pregnancy if there was no ejaculation?
I took 2 home pregnancy tests last Thursday and Friday, and the both came back negative.
What are my chances of a false negative?
If I take another HPT next week (6 weeks after my last period), if I were really pregnant, would it show already?
Thanks!
