Beta results

I just got the call I have been anxiously waiting for all day.  My beta is 68.5, I am definately pregnant!! I’m so excited but now I’ll find everything to worry about that I can.  First thing is that at 12 or 13 dpo (more likely 13 dpo) I’m sitting at the low end of “ok betas”.  I go back Wednesday for a second beta to make sure the number is doubling.  If that goes well then I’ll go at 7 weeks for an ultrasound.  We should be able to see a heartbeat by then.  Omg – can this really be happening??
