ovarian cyst

hi mga mommies, i was diagnosed to have an ovarian cyst last 2015 while pregnant with my second, kaya lng nagmiscarriage ako...so hindi ko na napafollow up check up...now that i am on my third pregnancy,3rd mo. ..nakita ulit sa ultrasound ung cyst and lumalaki daw xa... ang sabi ni ob, if it gets bigger,sa 5th month ko, i need surgery to remove it... natry niyo n ba ang ganito?
