Reset glow?

Jenn • I`m 36 Dh is 40 and we have 2 girls age 6 and 15 months 🥰
I said my preg test was positive even though it's just a super faint, possibly evap line. I changed it back and changed my status back to ttc, but now all the coloured dates for ovulation/expected af are gone from my calendar and bbt chart! How do I get them back? It has also changed my last period to spotting. Thanks
