Sayang, abdominal pain + dark red spotting kat 12 weeks tu tak boleh tunggu, please go to the hospital or call your gynae sekarang juga, okay? Even though the spotting was "normal" last time, this is different and kena check properly. A few of my mum friends had similar scares and doc checked them within the hour je, so don't worry la, just go cepat. Better safe than sorry when it comes to pregnancy. Semoga everything is fine!
