16 weeks 4 days mild cramping

Paige

I’ve had mild cramping all day in my lower abdomen where the baby is / lower back and tingling down my legs.. it isn’t like sharp or anything but it’s definitely there- I know the tingling can be caused by sciatic nerve pain and is really normal. But the cramping has me worried.. I’ve been drinking extra water and laying down.. could this dull pain be growing pains in my uterus ? No bleeding or anything, but still just any cramping feeling worried me. Any moms go through this and say it’s normal?
