Itchy Vagina

My vagina itches from having protected sex...After I had sex with my partner with a condom I felt itchy after he paused during sex to take break inside me instead of easing it out he went deeper felt good but afterwards it cramped like hell and I piss constantly for 48 hours and couldn't hold my urine properly...When I pissed it hurt. Then after that time period was over my vagina started itching harshly and then I was thought maybe it's a yeast infection...then my friend told me I'm probably healing that's why it itches so much...P.S I'm not allergic to condoms at all...
