I'm 20 years old, female. I don't know what's going on. I had unprotected sex about 4 weeks ago, I got my period a week later. Had sex again. Exactly one week after my period ended, I started spotting. It was brown/light pink at first and then got more red in color with what appeared to be some blood clots. Not enough to fill a pad but enough that I needed a pad instead of liner to feel more comfortable and just in case. This spotting has been going on for 7 days now. About three days ago I started having to vomit at the same time each night. Some light cramping, nothing compared to what my period normally feels like which is what concerns me. I started having periods when I was 8 and I've never had anything like this and especially nothing that's lasted this long. My period is supposed to come in 12 more days. I went to the doctor 2 days ago and they weren't very comforting or helpful at all and was told 1) could be I'm pregnant but it's too soon to tell wait 2 more weeks and we'll see what happens 2) normal period could have been implantation and now this is a complication but too soon to tell 3) could be normal but still too soon to tell. So I'm just nervous and concerned and going to the doctor was unhelpful I plan on going elsewhere but I have to call around and find someone so I'm hoping someone will have an experience similar and might have an idea. I'm not experiencing any high level of stress, I'm on birth control but it's the non hormonal one and I've been on this one for about a year and again still no complications ever like this, taken same time everyday, again never spotting from it. Always normal and doctor said unlikely it's making an appearance now. I'm just very confused and a bit nervous.
