Hi I'm 18 years of age, my significant other and I had protected sex as he was pulling out he took of the condom so he could put his specimen on my stomach area but it went all over the place. I was scared to think it went on my vaginal area, so I checked and it was there. I took plan b right after that and I got my period like 6 days later, but it ended 3 days earlier than it normally does, but after my period I started to get this dark brown to black color of mucus, it's been happening for 4 to 5 days now, and I don't know what it could be, I'm scared to think that it could be implantation bleeding... I so scared I need help please put your input. I made an appointment, but it's not tell the 22nd of this month.
