A month ago my now ex and I. Messed around basicallly it was genital contact but his penis never touched my gaginal opening or never went inside it stayed up by my clitoris in an upward motion& when I felt this I pushed him off me. Ever since I've been worrying about pregnancy. I understand there is slight chance but there was no ejaculation and I was seen there were no fluids or precum on his penis but I was still worried a week later I came on my period but it wasn't super heavy like it normally is it was lighter. It started off brown and turned to like a bright red but still wasn't heavy . I worried it could have been implantaion bleeding but it coulda been my period but I had been stressing for two months so I'm not sure I can't get access to a pregnancy test yet so I'm waiting for my period which is due in about a week. I had my normal clear whitish discharge that I get before I come one& I have sore nipples I'm very afraid and idk what to do .. any explanation
