How many positive beta's before ultrasound?

[nyfoodie]

My first beta at 11dp3dt was 324. 15 dp3dt it was 1333. The clinic said it was excellent and to make an appointment for an ultrasound two weeks from today at which point I would be six weeks pregnant. I am nervous they are not testing my beta again. What if something goes wrong in the 2 weeks? What is the norm for number of betas before an ultrasound? Anyone had just 2 betas? This is my second IVF, the first i had a very low first beta and they had to induce miscarriage with methotrexate as beta kept rising abnormally. Would love feedback from anyone who has goen through this...

Just be prepared to only see gestacional and yolk sac. You might not get heartbeat till after 6 weeks. good luck.

Hi, thx for your response. I called back the RE's office and they explained they don't do betas after a 1000 because the rise after that does not convey any information. They suggested to do an earlier ultrasound at 5 weeks instead since I'm paranoid!

My first clinic only did two betas and the 6 week ultrasound
My next clinic did the firts two betas - then one each week of 4 and 5 before u/s
the next clinic did two only and u/s at 6 weeks - he believed only money hungry places did more (and I hated it after getting accustomed to those reassuring numbers)
this time - I used my clinics orders and asked my reg ob/gyn to order some in betweem so I got lots which gave me peace of mind
good luck
