I'm not sure about before you give birth but I know after I had my first I would bleed a little Every time I did #2 for a while. You may just have a scratch/tear from a large or hard poo. It will bleed a little each time until it heals, you can try stool softeners so it won't irritate the place that's healing.
Thanks you guys.. Just a bit hard to use #2 feel little pain when trying push..
Well thankfully I haven't had any this pregnancy, but if it is hemorrhoids I know there are ways to alleviate them like putting your legs on a stool or step when you are in the restroom and there are also things in the pharmacy but I'm not sure what is safe or not to use during pregnancy. hope this helps!
