Sabar ye hun, ni memang common dekat trimester akhir tapi tetap kena perhatikan! Few of my mum friends ngalami ni jugak, especially kalau baby dah besar dan compress perut. Tapi sebab ada sakit bawah perut tu (even if sporadic), better check with your doctor or midwife cepat sikit ye, just to make sure everything okay, especially with the vomiting and frequent trips to the loo. Boleh jadi reflux or indigestion ke, boleh jadi Braxton Hicks contraction, so better safe than sorry at 36 weeks. In the meantime, try makan kecil2 je, banyak minum air, and track bila exactly you get the pain and muntah supaya you can describe clearly to doctor. Hang in there, you're so close to the finish line!
