Hi all I'm 31 weeks pregnant with baby no 3. Sorry for the tmi post lol went to the loo yesterday and a blob of mucus dropped in to the toilet... and has happened twice today...? It isn't unusual for me to get a lot of discharge/mucus but it's never plopped into the toilet before! I have had horrible lower back pain but spoke to the midwife yesterday and I'm pretty sure my iron tablets are irritating my stomach.
