So far so good

I had some betas last week... 18 dpo my level was 1051, and day 20 it had risen to 2345. A doubling time of about 40 hrs. Pretty good! But I still have those nagging thoughts that all is not well. Yesterday I didn't feel pregnant at all. Until the end of the day when I took my bra off and it HURT! Ohhh the big heavy boobies!! I see my doctor again tomorrow and she will order some more blood tests, and talk about when to do an ultrasound (depending on the blood results). It's all so painstakingly SLOW!!
