Diarrhea like nausea

So we just started ttc a little while ago and this morning I was feeling super sick and have been off and on all day. But it's not necessarily a vomit type nausea, it's more of a nausea from diarrhea. I got into work and basically had to wrap up into a ball because I felt so gross. But at the moment I feel fine. It was definitely worse this morning. I've also just felt super bloated. I'm almost to my peak ovulation. My mom told me that she got pregnant immediately each time they decided to try so I'm wondering if I could already be and it's just super early signs?
