This morning when I woke up I was bursting for the toilet (both ways, sorry tmi!) and I noticed my tummy/uterus was sticking out and hard! No pain, no changes in anything else, baby still jumping around afterwards as normal. Didn't last long. I've noticed this a couple of times before over the past several weeks but only after sex (Sorry again for tmi!). I'm wondering if these are braxton hicks? They don't hurt at all, maybe a slight tingling. Dr Google says you can potentially feel them from 20 weeks especially if it's not your first. This is my first baby however I seem to be a few weeks ahead of the books for everything - I felt movement from 14 weeks!
Please reassure me, my anxiety from the early days is returning today in the form of worrying about preterm labour!
