Hi Leila,
Like Daniellec said - my understanding is that MC can happen at any time but is more common in the first 12 weeks.

It is definitley normal to be stressed about the wellbeing of your baby. I was extremely stressed around week 9 (when my MS stopped) because that's when my sister had a MC the year before.

Luckily both scans since then have shown everything to be fine and suprisingly, time has been flying! I think it's important to try and stay positive (once again, easier said than done!)

Congratulations and wishing you all the best with your pregnancy. Xx
