Aiyoh I understand lah, the waiting is the hardest part especially when doctor say "not well-formed", but honestly if no bleeding or spotting after a week, that's a good sign and you should feel a bit better about it! A few of us mums went through similar scares early on and the baby turned out perfectly fine, so don't torture yourself too much lah until week 8 check. Try to keep yourself busy with your toddler (easier said than done I know!) and just take it as good news that everything's stayed stable so far, but definitely go for that 8-week scan to confirm everything's progressing properly, ok?
