If it's not a fertile day you cannot get pregnant. If your cycles are always 28 days, then it is extremely unlikely that Cycle Day 6 would be a fertile day. Emergency Contraception would prevent ovulation and then would likely disrupt your cycle so you would not know when to expect subsequent periods. I don't think it is necessary. But you do need to be careful in the future. If you are not 'sexually active', and are not intending to be, why was wearing a condom, and then why did he take it off before he ejaculated? It is best to use full terms rather than initials, especially first time, and particularly when using slang (which varies across the world), and be explicit. I assume by your 'p' you meant 'püssy' (but that can be vague) and maybe by 'fupa' you mean 'Fat Upper Pubic Area' (a wide area of protruding fat in the upper pubic region), but that is also vague (and you might not be very fat). 'Very little blood had come out like from a cut' from where? What do you mean? Could the ache be from him penetrating your anus (if he did)?
He was he was wearing a condum because we were messing around and I didint want be worrying worse than what I am now like with the whole Precum etc and also because I don’t want to catch like hiv or something and he took it off when we just stopped fooling around I didint feel like doing anything anymore I had already started worrying and he wanted to jerk off and cum but when he immediately cummed he didint touch me at all and he put his over the cum I then gave him hand sanitizer. P for p***y it’s cuz I thought the website would censor the word and I’m not fat , but I googled it and it said that’s what the top is called and he didint penetrate my anus at all I think it’s a trauma or a small cut from inside my vagina because he had fingered me too kinda fast and a bit rough
If he fingered you too fast and rough (why??) then he has probably ruptured your hymen (which could have caused the blood you saw) and caused an ache in your pelvic region.
While I know what you mean by 'p.ussy', the term is used rather generally, and terms like the vagina, clitoris (clit), labia majora/minora (outer/inner lips), & uterus (womb) are more specific. If you need help understanding these things, then just ask (privately if necessary).
Your pelvis is the lower part of the trunk of your body between the abdomen and the thighs (or the skeletal part in it). You could give a link to a picture. But it must be one from an educational site, and certainly not a picture of your own body.
It could well be that you have an infection. The danger of infection is the reason females should wipe from front to back after going to the toilet.
