hi augustbee, i definitely didn't know it too! until i had it for both my previous pregnancies.. then now i learn not to have it done, so i dun mind having a later first visit to gynae. I dun think it happens for everyone, but i think im not used to it so i got stressed and it might have resulted in the spotting too..after i mentioned to gynae, i was prescribed duphaston. The spotting was somewhat like urs, took a few days to clear. When i read online, many say its normal, but i dun think i wanna take the risk again..
For the gynaes i went to, before 12 wks, they will do v u/s as they claim can see better since foetus still small.
When's ur next check up?
