Chloe • love of my life 2012❤ baby girl 2017👨‍👩‍👧❤
Im 16 weeks on thursday, i think i found babys heartbeat however when comparing it to my own recorded the babys sounds alot slower than mines, like the beats are alot more spaced out, is this normal or am i just finding my own, found it down near the top of my hairline, thanks in advance x
