Hi my name is meme and I am 19 years old. I started to have sypmtoms of another period(bleeding brown/red, abdominal pain, backpain) just one week after having my mentrual cycle! I had unprotected sex about three times, he is not my bf, but he is only the second guy ive had sex with. Could I be pregnant? I am scared. Im stupid for having unprotected sex :( I had my period on may six and ended on the 12th I had sex on the 13th and took a plan b pill. That pill will be my third pill that I took recently. last month in april I had my period on the 4th. And had unprotected sex on the 28th I believe nd did not take plan b pill till 3 days later. He says that he pulls out but im not really sexually active and I hope I did not get pregnant from precum. Please give answer asap thanks.
