Please help! 6 dpo

I'm 6 dpo and I've been having cramping from side to side sometimes in the front & sometimes in my lower back. I'm not due for af until the 15th , my boyfriend and I had sex twice during my fertile week on 33% & 8 % , he pulled out , but I felt something ooze out in me during sex before he ejaculated & then the second time he ejaculated on my leg and it oozed onto my vagina. We're not trying to conceive but then again not avoiding it. So I'm not really stressed, just curious.1
