Time between betas

[mrssqueegy]

If you had to go for betas, did you go exactly 48 hours apart, or just two days apart but not at the same time each day?

The lab told me it had to be as close to 48 hrs as possible. I went Friday at 4:30 and again Sunday at 4:30.

I had my first betas on a Monday morning, and my second the following Friday morning. Apparently, my RE doesn't subscribe to the whole "48 hours apart" thing!

My office has me on a weekly schedule. This is also my first experience with the b/w so I'm just along for the ride.

I did 3 they were 2 days apart but not exactly 48 hours

Thanks for all the replies ladies. I went today around 11am which was the same time as my one on Friday. My OB had said 48 hours but I wasn't sure how strict it was. Now let the waiting begin.

Just wanted to let everyone know they do have handy beta calculators online, so you can have a program do the math for you and figure out your doubling time, regardless of the spacing of the betas. www.countdowntopregnancy.com/tools/beta_doubling_calculator.php
But dont freak out too much if it doesnt exactly double in 48 hours, some drs say 72 hours is fine. I think it is more of a general progression thing.

They are happiest with doubling, but 60% in 48 hours is acceptable. Lower than that is concerning, but not dooming. They'll likely continue to repeat until they are high enough to u/s.
