Early Pregnancy Symptoms?

I lost my virginity 10 days ago to be exact and there was a little spotting that was pinkish which I know is normal. I was due my period in 4 days from the day I had sex. However the next morning when we did it again I noticed I had started bleeding heavily an hour later which lasted 6 days, and had cramps but the bleeding felt a little different than normal and was much darker than the spotting. Did I get my period early? I’m experiencing cramps and ovary burning pain that comes and goes so could I be pregnant at all? We used a condom and it didn’t break. It’s a little bit too early to take a test I think. Anyone had a similar experience? I’m not on the pill but I’m definitely gonna be going on it after this.
