Possible TMI but an important health/fertility milestone.

I got my period today. One week and two days before Lexi's first birthday. Almost 21 months to the day since my last one. I'm having so many emotional reactions. Sadness, because somehow it feels like a mark of the end of Lexi's babyhood, relief and hope because it feels like my body is doing what it should, which bodes well for hope for more babies...and I'm not sure what else. I do know that I feel so thankful for Lexi and all I'm blessed with through her and the miracle that is her life every day. I think this reminds me of that too.
