I'm 23 weeks pregnant and blood work and u/s were all perfect just for one thing they seen a reflection at babies heart that interfered with there ultrasound machine at my 22 week u/s, my doc told me not to worry but as a mom I'm really worried, baby's heart best was 160 bpm and nothing else abnormal came up, we are waiting for a specialist to get back to us to see if it's worth seeing him, till then I need some advise, all my screening tests came back normal.
