Spotting is common but need to be aware of the color . Usually is brown . If fresh red, no gd. U can go gynae and ask for support. Oral med is call Duphaston. Progrestrone jab is faster effect. But even if it's brown, if it's alot, don't take it too lightly. Take support to have a piece of mind.
When I was wk5, I had red bleeding. I rushed to KKH24hr at midnight for a jab. I kiasu also ask for duphaston. At the same time just to scan to make sure sac is still there.
