TTC after BC

Alyssa

Hi, I'm 19 years old my husband and I made the decision to start trying for a baby! I was on birth control (pill) for about 2 1/2 years and just stopped it about a month and a half ago. A couple weeks ago I had what seemed like a 3 day period which is odd for me even before I started birth control. I've ALWAYS had 7 day periods. We thought maybe it was implantation bleeding but all pregnancy tests have been negative. When will I be able to start conceiving if that bleeding was indeed a period? I wouldn't know when my next period would be as I had an EXTREMELY irregular period before starting my BC! Any advice helps thank you!
