Discharge????

I was supposed to get my period yesterday but didn’t. I feel a little off, but necessarily I’m always nauseous around my period, but it’s worse. Been peeing a lot, moody, and then yesterday my stomach was hurting so bad on the right side and it had me crying really bad. Then this is my discharge today, it’s very clear and stretchy. My period is always on time and I never get discharge like this around my period either. I know I could be stressing and making these symptoms because we’ve been trying since March.
