I need help...

I am currently 10DPO and am backed up something severe...

I mean I can not pooo. I have really bad pains in my pelvis and back (could just be af) - but I can not do a number two and i feel like I need to.

I can not even remember the last time I was constipated

Can anyone tell me what I can take -that would be safe if god willing I was pregnant I know prunes but I need something that will give me releif quick if possible
