Cycle days missing after putting "pregnant"

I got my BFP (yay!) so I put a positive pregnancy test in for that day. Glow changed my status to pregnant, but when I went back to look at my cycles it had changed "cycle days" to N/A and got rid of my period information!
​I need to take that to my gyno, so I quickly changed back to "trying to conceive." My periods came back, but the Cycle days still show N/A. I tried to add a period for this month, and future cycle days show, but not my past ones. It's really inconvenient when trying to figure out the math and my due date! HELP!
