Hi guys I was just wondering if you could help me out I’m on birth control and I last had sex November 11 we used a condom and I don’t think there was any problems but I’ve just been feeling really tired lately and that first week I was nauseous and dizzy. But I took a pregnancy test on December 10th so basically 4 weeks later and it was negative and I took it in the morning I’m just wondering if this is true positive cause I’m 17 and people say if you are younger it doesn’t show up till way later. That’s all thanks :)
