Heartbeat Monitor / Fetal Doppler

hello! yes i bought 1 and is super good! but must wait till 20 weeks or more then can really detect the heartbeat. bcoz i had stillbirth previously, so i used this to check the heartbeat so im less paranoid. it is not dangerous at all. the only warning is some ppl may not know how to use and hence misjudged. but from my own experience, its actually quite easy and it really only detects baby heartbeat and nth else. before that i tried on my own heartbeat first. anw i have delivered my baby. if u want the Fetal Doppler, i can give it to u as blessing :) let me know
