OH Baby!!! WELCOME BRENCHEL BABY #2! 💕 Happy Mother’s Day! We have a lot to celebrate this year 😍 As a mom it’s my day to celebrate Adora & OMG baby #2!! 🙌🤰 I can’t believe I’m pregnant! We’ve been trying for a while to have another and just wanted to do a special shout out for the bracelet and app from @avawomen because after our first cycle using them, we got pregnant! It tracks your cycle and lets you know based on psychological changes in your breathing, heart rate and temperature when you’re ovulating and when the 5 best days to conceive are! You can only guess what happened from there 😉 Did you know that the 2-3 days before ovulation are when you have the best chance of getting pregnant ladies?! That’s a short window!! I can also use Ava to track my pregnancy 🤰 and measure all the little details throughout!❤️🙌 I can’t wait for what this pregnancy has in store for us!!!! Check out my article in @people for more details about what it’s like being pregnant in quarantine and how this pregnancy has been so much different from my first, especially being over 35 now 😲 Use code RACHELRV for $20 off your purchase until the end of the summer ☀️ Link in bio 😎#avapartner
