Help!

I’m supposed to start my period tomorrow, and I’m having mild PMS symptoms (slight cramping/pressure & mild bloating). I usually start cramping 2-3 days before my period starts and I bloat like crazy, so I’m wondering if I’m pregnant? Any others who’ve had the same? My husband and I had sex 3 of my fertile days, one being 12 hours after my “peak.” I truly thought I was pregnant last month, so I’m afraid to get my hopes up...
