I found out I'm pregnant for the first time after 18 months TTC and <a href="https://glowing.com/glow-fertility-program">IVF</a> on Wednesday!! L I understand how the weeks work.. I think. I'm 4+1 today, so I believe that means I'm in my 5th week. My question is, how do you read the apps and books that share <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby development</a> by week? Meaning if I want to know what happening this week with my baby do I look at week 4 or week 5? This has always been a confusion of mine. Thanks for any and all help!!
