Eh don't worry, quite normal actually! Masa orang masukkan speculum (muncung itik tu), the cervix memang very sensitive and bleeds easily during pregnancy sebab ada extra blood flow. A few mummies I know ada experience the same thing, perdarahan and cramping right after the check, even though sebelum tu okay je. Since doktor dah confirm baby okay and uri okay, likely it's just from the examination itself.
The spotting and extra bleeding can continue for a few hours or even a day or two after, especially kalau doktur kena insert berapa kali pun. The urge to pee tu boleh jadi dari the irritation or just anxiety about the bleeding, very common feeling. Jangan risau sangat, tapi kalau darah jadi heavier (macam period flow or ada gumpalan besar), or rasa cramping yang teruk, better call your doctor or go back PAC okay? They know your situation best and can reassure you properly.
