Morph scan

Rachelle • Mother to 3 daughters and 3 sons. Mother to 3 angels taken early in pregnancy. Currently pregnant with my number 7.
So I had my morph scan a week ago. I had my antenatal app today where the dr told me my belly was contracting during the scan. I asked if it were just Braxton hicks and she said they weren't. I was wondering if this has happened to anyone else and did you end up going into preterm labor cos of it? Thankyou.
