Thanks for the ovia recommendations, I'll check it out!
I had my 20 week scan today and found out we're having a boy! So many boys in this group so far that I'm not surprised!
The only issue was with one of my uterine arteries, the blood flow level was very slightly high (I think that's what she said!). So I'll be monitored, two more scans and I think a clinic appointment where they will prescribe low doses of aspirin. Apparently the issue can lead to high blood pressure and preeclampsia. The sonogorapher said not to panic and the aspirin will make sure it's okay.
Has anyone else had the same information? I'm not really panicked and I like the idea of two extra scans but after a quick google it does sound a bit scarier than it did when we were told.
