How to tell your BFF that you have a BFP?

Not sure where to post this...

My friend and I have both been actively TTC and have continued to update each other in every moment of our TTC... well I finally got my BFP but she’s about to undergo some <a href="https://glowing.com/glow-fertility-program">fertility treatment</a> and am just not sure how to handle it. Should I tell her after, do I wait the 12 weeks? Is text better so she can process on her own?
