Hi OP
It’s horrible isn’t it? I’ve suffered with it throughout my pregnancy. Firstly, have you spoke to your GP about the bleeding? It’s likely piles but I’d get that checked ASAP and they can prescribe some cream if it’s that.
Constipation side - I’ve found that certain foods can help however, I’m on ondansetron for sickness which blocks you up more - so I use movicol and lactulose to help me ‘go’ are you on any meds which could be contributing to the constipation? I.e iron, sickness tablets etc?
Food wise, prunes, apricots and apples are all good. Oats are also good. Drinking water like medicine helps too, literally you want to drink as much as possible it helps soften things.
As I mentioned medication wise movicol/lactulose/CosmoCol and laxido are all safe to take during pregnancy & you can buy over the counter. I have also used Glycerin suppositories (again you can get OTC) they will help soften and make you go, especially if you’ve struggled to go for a few days. The only problem is that if the ‘blockage’ isn’t lower enough, they won’t help.
And finally! I’d recommend using a stool or a ‘poop stool’ (you can buy on eBay/amazon) and that just puts you in a natural, squating like position to help you go more easily. I found baths quite comfortable too whilst constipated.
Hope you feel better soon!
