Sayang, ini serious medical matter, please see your doctor or OB-GYN straightaway, okay? They need to check you properly and monitor your pregnancy closely. Honestly, a few of my mum friends have had different situations during pregnancy and each case is totally different depending on timing and medical history. This is really one where you can't risk guessing, your doctor will advise what's best for you and baby. Jangan delay, go see them soon ya
