Pregnant after IF

Advice- non doubling betas

hi All! I was active on the IF board this year through August when our first PGS FET failed. 

Now I switched REs and did a Fresh Transfer of 3 embryos on Day 3 on December 8. 

At 10 dp3dt I had a beta of 199. 48 hours later at 12 dp3dt the beta was 467. So yay!

they did a 3rd beta on 14dp3dt and it was only 785. So not double and a 68% increase. Doubling time of 64 hours. My RE said up to 72 hours is normal. 

He he also said it could be vanishing multiples. If you average across the time from 10 dp and 14 dp it was doubling every 48 hours.

Has anyone dealt with this and had a good outcome? I don't get another beta until Tuesday due to Christmas and Ultrasound next Friday.

  • Hey!!! I've been thinking about you!! So glad to see this update!! These are great betas!!! I wouldn't worry too much these are good! It's possible you have a vanishing one, I'm hoping u have a really strong nugget!!!  Keep us updated! Good luck!!!

  • @Ash_SE Hope you are doing well, and that non-doubling is due to a vanishing one.  Since I only had a single beta testing at 9dp5dt, I don't have a personal story to tell, but my acupuncturist told me that her betas did not double every 48 hours.  She went on to have a healthy child.  Hoping this is the case for you!
