My first time

So me and my boyfriend have been together for 8 months and I think my first time is going to be this weekend, could anyone tell me what it will be like and what i need to look out for? i’ve always been told i will bleed on the first time and it wont be enjoyable

what are my chances of getting pregnant if we have sex a day or two after my period?

he’s going to use a condom and pull-out.

plus i take a hormonal birth control within a 1 hour window of each other. i know with birth control it stops your ovulation but i’ve also heard of spontaneous ovulation, so knowing my luck i would ovulate on day 14 of my cycle which would be next saturday, i know i sound crazy for worrying about my pregnancy chances with using three methods but i am 17 and i absolutely do not need to get pregnant

i just really need someone to explain to me in depth how all this works because anything i research won’t give me an actual answer, it just says “oh well it could be a possibility” i basically need someone to tell me they had sex a day after and they are fine lol
