Annoyed & scared plz help "bleeding 2 weeks before period"

Long story short, years ago I was TTC but I've had dermoid cyst and have some parts of my ovary removed so I just figured I couldn't have kids. Now when I'm no longer trying I've hooked up with someone. He finished with no protection from either one of us "I can't get pregnant right?" And my period finished 4 days before. 6 days after that I started "spotting/bleeding" figured okay it's just my period starting weird I've never ever in my life have been early but okay. 4 days later I'm still dealing with this "bleeding/spotting" it's not enough blood for a tampon or a pad or even a panty liner. Just when I wipe. It's seemed to stay pretty pink when it's there sometimes it's not it seems to die out most of the day and appears more around the evening. No cramps and I usually get really bad cramps. I've been nauseous on and off since day 2 of it. And pretty sleepy, But that could just be nerves at this point. I either want it to go away, period just to come, or a positive. Anyone any advice please at this point??!!
