Went in for a checkup and heard the heartbeat today (10w4d), in the 170's she said ☺️.  My 3 year old son was even able to come in and have a listen, I'm just very relieved to have heard it again.  Been having headaches and that worried me a little; the night before my miscarriage I had a horrible migraine, so now anytime I get the slightest headache I freak out a little.  But all is good for now it seems!
