Hi! So I'm 15 and I'm really worried right now, so me and my boyfriend hadn't had sex since March 16th and 17th, yes we used protection both times, and I've had my period 4 times since then because it came 3 days after we had sex and so on. But me having really bad anxiety, I took tests and all were negative. But we have been messing around, no sex or anything, and my period is 3 days late, but two weeks ago I started Cymbalta (an anti-depressant) or aka Duloxetine, and I've read that some girls have missed their period or it's late or blah blah. I took a test Wednesday on the 28th and it was negative, like obviously negative. But I'm flipping out, and my boyfriend is confident that I'm not pregnant but this morning he sent me a text saying he knows I'm not pregnant but he's flipping out. I haven't had any symptoms and when I do have "symptoms" it's when I think about it and start flipping out and it's always nauesea but when I stop thinking about it, I'm fine. I can't go to the store because I'm on vacation with my family and we won't get back home till the 8th or 9th, Please help me, I'm scared to death.
