I'm 16, healthy. Havent been to an OB-GYN ever, but I'm scared I may be pregnant. I'm not late yet, but I will be in 4 days. I've been experiencing brownish-redish spotting which is not normal for me at all and alittle fatigue. I haven't had any other symptoms though. The last time I was intimate, it was the day after I had ended my last period. Is it possible for me to be pregnant?
