Elizabeth • Can not wait for our little bundle of joy!
Just found out today I'm pregnate! I was due for my period Monday. I have naproxen prescribed for menstursl cramps. I took 3 (250 mg) in the morning so I wouldn't get cramps. No period. I got cramps the next day. Took 3 naproxen. Did the same thing the next day. Still no period so I tested & it was a bfp.
My question is, is that going to harm anything? On the bottle, it says do not take if you're pregnate. I haven't taken any since I found out. I just want my baby to be okay.
