Welcome to the Pregnancy Microbiome Study!

Are you pregnant, or have you just given birth? Congratulations!

uBiome and HelloFlo are teaming up to study how the trillions of bacteria in our bodies shift during and after pregnancy. You can be part of this exciting research by ordering your kit below.

The first 50 kits are FREE, just use the discount code BABYLOVE at checkout today. After the first 50, you can join this study for just $59.

Find out which helpful bacteria you will pass to your baby

Bacteria from your vagina are passed to your baby during birth and breastfeeding to help keep her healthy and strong. By participating in this study, you can learn who they are, what they do, and how they shift during and after pregnancy.

Go citizen science!

We believe in the power of the crowd to accelerate scientific research. uBiome and HelloFlo have been featured in Wired, Scientific American, CNN, TEDMED, NPR, Fast Company, and the Oprah Magazine. But we can't do this study without you. Please join us!

How it works



We'll send you a home sampling kit that takes less than 2 minutes to use (and is not gross). It's super easy!



Our lab uses cutting-edge next generation DNA sequencing technology to identify your bacteria.


Citizen Science

HelloFlo and uBiome will share findings about the microbiome during pregnancy, for moms and babies everywhere!

Am I eligible?

You are eligible to participate if:

  1. 1. You are in your second or third trimester of pregnancy, or gave birth (vaginally) less than 4 weeks ago
  2. 2. You aren't currently having your period or post-birth bleeding
  3. 3. You don't have or haven't had cancer, endometriosis, ectopic pregnancy, HIV, other sexually transmitted diseases, ovarian cysts, or pelvic inflammatory disease.

    After ordering, we’ll send your kit straight to you. Collect your samples with a quick swab each time, and mail them back to us in the prepaid envelope. We will keep you posted on the results!

    Thank you (and your baby) so much for being part of this study.
