Ever since then I had a lot of pregnancy scare's. I just started my period two days ago and this is the very first time I ever seen it bright orange. But I have have a lot of red blood clots but i can understand why the blood is orange and the blood clots are not. I have sex a week be for my period could I pregnant and not know it or having a miscarriage and not know or an STD and not know it. Please help!!!
