Period was Feb 26-March 3rd. I have PCOS so no idea when I cycle , I started testing the day my tests came in ( ordered off amazon) . According to Premom , ovulation is in 9 days . My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> says ovulation is in 5 days . I've been tracking on my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> for 5 years so I feel like it's more accurate?
