This is totally lighthearted by the way!
Yesterday I went to an nhs birthing plan with about 8 or 9 other couples. When we were there my dh recognised one of the other couples through mutual friends so after the session had finished he introduced me to them.
They were lovely, we were chatting away and the other lady was due three days before me. She asked about my symptoms and said she'd only just this week had to start getting up in the night to wee and having disrupted sleep. Now I'm 34 weeks tomorrow and felt like the green eyed monster as I haven't sleep well since about 24 weeks! As well as having a bit of a rotten third trimester generally, I have a lot of pressure down there now, however this other lady was significantly taller than me.
I know everyone carries differently and I'm sure they'll be a mixed bag of responses, but I just wondered if you were shorter- did you give birth on time or were you earlier? I'm 5'2, as is my mum and she had me and my brother about a week early (which gives me hope for similar!)
