I had sexual intercourse on June 9 and June 21. My menstrual cycle does not come at the same time every month, but i was keeping track of my period every month and it seems to come around every 30, 31, 32, or 33 days. My last period was on June 2 to June 8. I started spotting on July 1. I was just wondering if i can get some tips if i conceived on June 9 or on June 21?
