3w6d - Nov 14 - 1st draw - 114

4w1d - Nov 16 - 2nd draw - 229

4w6d - Nov 21 - 3rd draw - 576

Notice the 5 day gap in the last 2 draws. 5 day span and it only rose by 347. Anyone have a similar situation and still end up with a healthy pregnancy? I have a history of miscarriages so I’m really trying not to freak out here.
