Thursday night, my partner came home from work feeling very ill and nauseous. He asked if I was okay because he felt something was off. I felt perfetly fine. That night, however I woke up with terrible cramping, which is highly unlikely this early in my cycle. I checked my chart and it seems I was 6dpo and we also bd on my ovulation date. During my first pregnancy I don't recall any cramping, but this time it was decently strong and lasted for at least a half hour. I normally only get cramps 1-2 days before Aunt Flo.

 Any opinions? 

Anyone have anything like this? Thanks so much ladies
