Taylor • 22 years old! TTC baby #1 with my husband!
My husband and I are TTC baby #1! We haven't really been able to try because I hadn't had a period since the middle of July. I finally started my period yesterday so we are praying we can figure out my ovulation days so that we have some sort of chance. When should I start taking ovulation tests and keeping records of BBT? Or should we just wing it this month and pray it's the month for us?
