Should I be worried?

I haven’t had sex in a while but I’ve been talking to this guy for a while and we ended up having sex last weekend so like 8 days ago.

I’m on birth control, I take June’s Fe and I’ve been on it since August. I’m pretty good at taking it and I take it everyday at 1:00 but we are all humans so sometimes I’m a couple hours late max but I’ve NEVER missed one!!. The days leading up to Sunday (when we had sex) was my placebo week and after we had sex it was time for me to start a new bc pack which I did but I started the new pack 2 hours later than supposed to. We used a condom and he seemed to know what he was doing and when he pulled out the cum was still inside of the condom so it worked I’m guessing? This was only my third time having sex so I’m still a newbie sorry!!

I’ve been having real bad bloating, period like cramps, hungry 24/7 and some pain down there kinda like a stretching or it’s been stretched out type of pain but it’s been 8 days!! I’ve had some other symptoms like back pain but maybe it’s just me psyching myself out? So I’m a little concerned... and should I be concerned about possibly getting pregnant from this situation? Thanks so much ladies!
