35 wks today and woke up around 4 am with mild dull cramps.. kept me up. But didn’t try and time bc I didn’t think too. Now I’m on my way to work and it’s still continuing. Very dull but I also feel nauseous.. what do I do ?! Just monitor or call dr? I am still working out and yesterday I did a longer workout than usual and I also deep cleaned my kitchen and living room .. and took maternity pics, where I lifted my son up multiple times.. which is almost a normal day for me but maybe I over did it ?
