I had sex without a condom on June 15th, 2016 (But i was on birth control), and got my period on June 16th, 2016. However, June 16th, i left to go travel internationally for 3 weeks, and returned on July 7th, 2016. I kind of didn't take my birth control properly those exact 3 weeks (But i took it). I had sex again without a condom on July 9th, 2016 (Saturday) the last night of my pack before my remembering week started (Sunday). My period was due July 14th, but i missed it. Can i be pregnant?
