Hi, I not sexually active, although once I had a guy ejaculate on my body but his semen did not enter my vagina. I had my period on time for the next two months, however on the third month,l my period has been extremely light for three days, which was followed by occasional spotting of bloody varying in pink to red and darker shades. This has been going on for more than 2 weeks now and I am extremely worried! Please help? I have also taken two home pregnancy tests, both have come out negative!
