Nauseated before postive

I'm currently ovulating, my husband and I had sex a couple days before and we didn't pull out. I took the plan b, but I kinda knew it might be too late since I knew I was going to start ovulating soon.

Today, I just feel weird. It's not like morning sickness but I definitely feel a bit of nausea. I was able to tell i was going to be pregnant with my last two pregnancies and something in my gut is telling me this is a sign too lol. And infact I got a positive at 5dpo with my last baby because I just knew.

So I basically just want to know if anyone else has felt this way? Or maybe I actually just don't feel good??

BTW, we knew plan b may or may not work. I think I took it like 2 days before my estimated ovulation day, but within the right amount of time we needed. We basically did the deed that night and I took it the next afternoon. So yes, I know it could fail at this point, and we are ok if it does but weren't planning for it.
