I need some advice

So last week on Friday i lost my virginity after them me and my partner was having sex for 3 days straight. This Monday when I woke up I was abdominal pains and still kinda am till this day(I Think they are going away slowly) I ask my friend she said that is normal bc it’s your first time having sex. He pull out everytime and he make sure that it wasn’t cum on my vagina and we both wash up and pee after we was done. I just wonder did anyone else had this problem and plus I am on the pills and I take them everyday. I JUST NEED SOME ADVICE IF IM GOOD ?
