Hi, I am a mother of two. With my first child I missed my period for the first 3 months following giving birth. I had my second child in April and have had normal periods since. Expect I didn't get a period for the month of August. I'm very worried. My period was due at the end of the month so it is about 10 days late. The last time we had sex was around 3 weeks ago. No condoms were used just withdrawl. I took 2 test in the past week which were negative. Do you think I'm pregnant or is this just an irregular period?
