@sazzlondon There's some stuff on the NHS website about pelvic floor exercises and how to do them: https://www.nhs.uk/pregnancy/keeping-well/exercise/
I go through phases of being really good and doing them every day, and then sometimes I forget for ages. I do always remember to try and tighten my pelvic floor whenever I cough or sneeze, and as I have hay fever I've had lots of opportunities to do that over the last few weeks. 😂
I'm another who is peeing more frequently, solidarity with everyone who gets stressed out about being away from a toilet for more than half an hour! I can't remember the last time I made it through the night without having to get up for a wee, and sometimes I end up doing lots of really tiny pees in a short space of time - that's when I assume baby is sitting a bit lower and squishing my bladder. Last night I was getting ready to go the gym, I went for a wee twice in 20 minutes while I was at home and then again 15 minutes after that when I arrived at the gym!
