it's been a hell of a month.

so about three weeks ago i went to the obgyn after having a positive at home pregnancy test, just to find out i had a miscarriage. it's been so hard on me and it made me want to give up overall. i've been just focusing on my health and making sure i'm healthy enough to carry a baby. any advice on how i should go about trying again? vitamins? i have another appointment on friday for an ultrasound to check my ovaries. i'm so nervous.
