Weird sex question 🙈

SH🌼

So I delivered my baby vaginally 10 days ago, and the past couple of days I have been super horny. My partner and I were kissing, and I managed to orgasm just from that 😂 anyways, afterwards I've been having really intense pains almost like period pains. They're super painful, and I don't know whether I should be worried or not. Has this happened to anyone else?
