Help pls

I lost my virginity and before it I had some spotting since my period was due in two days. We used protection and nothing broke and he also pulled out and so I'm confident that we were okay. I got my period after but the flow is very light and the blood is darker but it's not like spotting it's just a light flow. When I wipe it's like fresh red blood though and this has been happening for like 2-3 days. Is this normal considering it was my first time and having sex can change your cycle a bit?
