Wa'alaikumassalam sis! Mmg common la buasir luaran masa pregnant sebab hormon dan tekanan, and kalau dah ada memang boleh worse. A few of my mum friends ada the same issue, mostly dorang cakap pakai Anusol atau Preparation H helps with the swelling, tapi kena konsist pakai. Most important is jaga diet (lots of water and fibre!) so tak keras sangat when buang air, because straining tu yang bikin worse. Since you're pregnant, better check with your doctor or gynae for products that are safe, they usually OK recommend suppositories or creams yang pregnancy-safe, so jangan take chances with random products. Hopefully after delivery it gets better!
