So my last mestral cycle was wrong!

So I got pregnant the week after my cycle!! Turns out I am a week behind what my menstral cycle predicted. I'm supposed to be 2 months and 6 days. Instead on Monday they measured baby as 7weeks and 3 days, tomorrow I'm exactly 2 months and 0days. So I've come to the conclusion I convinced a week late. So as further ado.. here is baby #2 (at 7w, 3d) a strong heart rate of 158. I've had a baby girl and want a baby boy and I asked my doctor about the whole "can you tell the difference between the heart rate of the baby for gender" She said that is a myth. So here is to hoping!!! Love that it's a clear pic of the baby and the sac. Baby almost looks upside down.
