2nd trimester gusi berdarah

Hi mommies. This is my 4th pregnancy. First time experience gusi berdarah masa pregnant. Im currently in my second trimester. Ada sesiapa pernah experience tak gusi berdarah/ bengkak macam i? I google, katanya pregnancy gingivitis. Taktau la betul ke tak. And another thing, boleh pergi dental ke during pregnancy? Anyone pernah ada experience? #pleasehelp
