you monitor first. if it persists, beta go straight to hospital.
My gynae told me if you have fresh blood spotting, is not so good, gotto go hospital immediately. if is not fresh blood but like dark brown, it could be old blood inside the womb and is rather harmless.
For my first preg, I had fresh blood spotting and gynae asked me to bed rest and after 1 hour, still have, then go hospital. but was lucky thatit was just one episode so no harm done.
For my second preg, i had fresh blood spotting again. despite me bed resting, still get the spotting, went to hospital. was told there was no heartbeat and in the end, i had a miscarriage.
in any case, go by your instinct. if you dun feel good, go straight to hospital. beta be safe than sorry.
