Joining you all.....

mrsfaz2be

I am currently 5 weeks pregnant with child number 2 and would like to join you all.  I was on the SecondaryIF board, however dealt with fertility issues with my first as well.  We were on femara for DS1 and this pregnancy as well.  I had a miscarriage two months ago, so I am a little nervous but hopeful. My first beta at 13 or 14 dpo was 120 and today at 19 or 20dpo the beta was 1409.  The doubling time is 42hours. Does anyone know what a normal doubling time is? I am finding a lot of conflicting information online about this and didnt have a second beta done with my first.
