Freaking out

Someone please reassure me!! I’ve been on the combination pill for many years now and I never miss or take any late. I switched pills about a year ago to junel fe, and the past few months I’ve noticed light spotting like a week before my period. Also I spot after sex, and I notice when that happens my boyfriend usually hits my cervix during sex. He always pulls out, but I’m sure there have been times where some semen would get in me. Please ease my mind someone! In the past I would let my boyfriend cum inside me but I never had scares. This spotting is scaring me.
