Heavy lifting and cramps?

My period is due in 3 days according to glow. This will by my second period since my son’s birth. We’re trying for baby #2, we only tried a few times this month so I didn’t think I’d be pregnant because it took a while for our son.

Well, tonight I was helping my husband

rearrange our living room and after moving furniture and heavy lifting I started to get cramps. I remember when I was pregnant that I would get cramps in early pregnancy when I was doing more extraneous things.

I’m wondering if anyone notices cramps more while doing extraneous things as a sign of their period coming or as an early pregnancy symptom? I usually get persistent cramps when my period is about to show, but I haven’t had cramps other than after the lifting.

Any thoughts appreciated. Thank you!
