I am 19 yrs old and today I turn 8weeks. I havent yet gone to the drs, but on the 5th I have an appointment. I have been taking some gummy vitamins 2 a day. When I was 16 I had a miscarriage at about a month in a half, so im really worried this time around about doing everything right. Anything I should know or do this time to prevent anything from happening ? Thanks for the advise :)
