My Dr gave me prenatal vitamins with a stool softner. I take my regular ones unless I'm constipated then I start my others which helps keep me regular
Ohh yeah, definitely know how you feel, lol! Try eating a fiber one bar a day and upping your fiber intake, definitely keep up with the prenatals and see if extra fiber helps, if not then ask your dr about a safe medicine to help you go!
I have the same problem it is not just the vitamins it's the hormones as well, you need more water and lots of fiber. Benefiber is a good choice also my dr recommended, glycerin suppositories and Senokot it is a vegetable based lax that is safe during pregancy. Talk to your dr the first thing they will say is are tough getting enough water :) good luck also otc you can try warm prune juice 4 oz or so a couple times a day had a nurse suggest that remedy.
Constipation is common during pregnancy and sometimes it just depends on what you eat. Like spicy food could go right thru you and other things not so much. How's your diet.
