I am 11w1d and i have to wait 4 weeks to be able to hear the heartbeat for the first time. One of my friends just lost her baby at 10w because the baby had no heartbeat. It scares me that that might happen to me. Are there any good cheap fetal heart dopplers my fiancé and i can get to hear the heartbeat? None of the heartbeat apps on my phone can pick up the heartbeat yet
