Early pregnancy and upset stomach

I think I could be pregnant but I’m not going to test until Monday. I’ve been feeling a bit off though, just different. Especially the last couple days. I thought I had started my period but it was barely anything for 2-3 days and then it just stopped completely. Normally my period is 7-8 days and heavy. I’ve had a little soreness in my back for a few days and some light cramping off and on, especially at night.

But anyways, the last couple days I haven’t been feeling so hot off and on. Monday I felt sick to my stomach all day and had an upset tummy. No diarrhea or anything, just frequent bowel movements and stomach aches. The last two days I felt alright, but then tonight I have an upset stomach again. It’s not anything I ate I don’t think.

But has anyone felt an upset stomach and waves of nausea randomly right before finding out they were pregnant??

I really hope I am pregnant. I just need to wait to test because it’s too early at this point I feel.
