So I had unprotected sex with a guy last month & we did the pull out method. & I waited for my period but it was like reddish brown, so I’m not sure if it was really my period. & these past couple of days my stomach has been hurting SO BAD like cramps but before I get my period my stomach doesn’t hurt this bad. I’ve also been experiencing chest burns, stomach burns/sharp pain, I would take 9hr naps & still get tired, & my whole body would just hurt for no reason. & my mom knows that I had sex, so should I tell her that I want to take a pregnancy test?
