Hello… In general, I have a problem ? A strong constipation is bothering me, after childbirth I put in glycerin candles and now recently stool was hard after this when I go to the toilet it's red blood, I tried for 2 days not to go so that it healed, I think a crack there formed, but no, back to hard stool, it hurts badly, and I can't walk normally to the toilet … I drank Duflapak doesn't help only gas, candles make stool hard … Today I read that you can take Biscodial with caution, I took 2 tablets and waiting … Can you please tell me what laxatives can be taken during breastfeeding? So that the stool is soft or liquid ???
