Merry Christmas, mama! I know it's scary to feel something unusual down there, pero good thing you already have an appointment booked, that's the right move. Your OB will be able to check it properly and give you peace of mind, kaya don't worry too much in the meantime, okay? A few of us mums have had similar scares during pregnancy, and most of the time it's nothing serious, but only your doctor can tell for sure. Try to stay calm until your appointment, stress isn't good for you or baby. You did the right thing booking that visit!
