Does anyone else have this?

So my husband and I had sex last night and I was super wet like we didn’t have to foreplay like we usually do and then today I had weird cramps all day and waves of nauseous and headaches off and on. I’m not suppose to ovulate until the 5th so I don’t know what’s going on. Has anyone else had this happen to you?
