Agree with Razeena, usually will have a follow up scan. Did gynae prescribe u any duphaston pills? It is meant to support the thickening of uterus lining.
In the meantime, pls do complete bed rest if u can. do not squat and don’t carry heavy stuff.
Speaking from my experience… I did visit private gynae to ask for hormones jab as well. take care mummy, wish the best for u.
