Kylee • Im 19 and pregnant with baby #1
So this is baby number 1 for me and im just extreamly worried about having a misscarrige iv been trying for a baby for 13 months and according to my last period im 8 weeks but accourding to the transvaginal ultrasound im only 6 weeks which pushes me back into the misscarrige stage :( dr said baby has a healthy heart beat i seen the heart flickering and heard the heart beat its 132 bpm just wish i could see or hear or feel my baby 24 7 to know he or she is growing
