Cramping after sex

I had a tubal reversal 10/30. AF is due tomorrow, except my normal pms symptoms have totally been different this month, I don’t even want chocolate! 😉headaches instead, light nausea, cramps that ease when I drink a lot of water sense of smell very heightened. In early pregnancy has anyone gotten very crampy during and after sex? It went away after I laid down for a bit. We’ve bd many times since surgery & this has never happened. However this has never happened before. Here’s the test I took on Wednesday, I won’t test again till tomorrow in case AF arrives I don’t wanna wait another test.
