Could I be pregnant?

So me and my boyfriend had sex for the first time on Tuesday and then every day up until today (Sunday) we’ve used all the different methods like pulling out, condoms and nothing. I’m really scared I could be pregnant cause he never told me if he got cum in me. I’m on the depo shot and I know that is usually 99% effective but there is still a chance. What do you guys think? The shot stopped my period pretty much completely so I have no idea when my ovulation is. I pee every time after sex and I’ve had spotting every day. Do you think I should take a test in a few weeks just to be sure? I feel like I’m overthinking this and being really paranoid but I’m not ready to be pregnant.
