Jangan risau sangat, dear, vaginal dryness during pregnancy memang boleh berlaku walaupun ramai orang kata sepatutnya ada lebih discharge, sebab setiap badan perempuan adalah berbeza. My friend pun experienced something similar around her third trimester, and her doctor explained that hormone levels can fluctuate quite a bit towards the end, so dryness is not necessarily a red flag. The discharge you notice after intercourse tu pun most likely normal, during pregnancy, cervical discharge memang increases, so it can appear more noticeably after intimacy even if you feel dry beforehand. That said, do keep an eye on the colour and smell of the discharge, if it is milky-white or clear and odourless, generally it is considered harmless, but if there is anything unusual, please do check with your doctor or O&G specialist to be sure, especially at 33 weeks ya.
