I’m 19 and I had I had protected sex with my boyfriend for the first time on April 23. My period came about the 5 of April usually last about 4 days. My periods are very irregular cannot predict my next one my cycle is typically 30 -35. I believe I was ovulating all the wk from 19 until the 23 (most fertile). My question is we used a condom (it did not break) and he pull out with the condom on before he ejaculated. To be on the safe side after an hour and half I went to get plan B. Does plan B work during ovulation? What are the chances I can get pregnant? This month has been a stressful month, I been loosing weight, and exercising and now I'm stressing about being pregnant can this also delay my period?
