I've been getting Braxton-Hicks for a while now, I go a bit dizzy, have cramps and my stomach goes all tight. I get them if I've done too much or walked too much.
I've been quite emotional lately, nice to know I'm not alone there.
I've got my 20 week scan on Tuesday and I'm terrified!! I was the same with DS1. I'm a wreck! Everyone keeps saying are you excited to find out the sex, I have to keep reminding people it's not a gender scan it's an anomaly scan and very worrying!! I'm so anxious I can't wait until it's over
