I need help!!!!

I’m 17, had sex for the first time three months ago... my period was late for over a month then it came and ever since Ive had spotting though it’s very very light bleeding. (And also my discharge is white and pasty like really water down chalk rn there are no clumps or very very small ones. No itching or pain from it tho.) But My boyfriend would still finger me during my period or spotting and I’m not too sure if it made it worse. I took three pregnancy test in the past three months and they all can back negative but I’m still worried that I might be prego... IM VERY PARANOID. I looked it up on like that long periods or spotting means ur pregnant or a infection but I have no symptoms of both. But I’m still spotting and it’s been at least two months.... PLS someone help me!
