Precum during high ovulation

Hello, I’m honestly not sure what to think because I feel like my body has been all over the place but me and my boyfriend had sex about 8 days ago and it of course was unprotected and I was on my highest ovulation day and he pulled out very late (like the second he pulled out he came) and lately my body has been feeling off, I’m hungry all the time, emotional from time to time, slight cramps here and there and an upset stomach as well as sore boobs. Any thoughts??
