am I pregnant? please help ladies!!

okay ladies serious question. I'm 16 and my boyfriend and I had PROTECTED sex (idk if anything leaked out or anything like that though, he came twice into it but I think they are smaller loads) this morning and I am ovulating(9% of preg.) which I didn't know until later in the day. I used the bathroom right after sex like usual to help prevent UTIs but I was bleeding, like spotting, this is not my first time having sex. it's evening and I am still spotting. Is this normal? should I be worried? the last thing I want is a kid at my age and parents would killing me😫😭
