TMI in advance! Just want to know if this is common at this point- 
I’ve been lucky not to struggle too badly with constipation during pregnancy, and have managed to go at least once a day. But for the last few weeks, I’ve been pooping at least 4 times a day - no diarrhoea or anything. I do get a crampy feeling just before I need to ‘go’ and I’m waking up every night in the early hours to go to the toilet also which has never happened before. I mentioned it to my MW a couple of weeks ago and she shrugged it off as ‘one of those things’. I’m starting to feel quite uncomfortable with it and have developed piles which I don’t think the frequent bathroom visits is helping!
Has anyone else experienced this?
