Hi everyone,

I'm new to this but I've been ttc for two years. I've been tracking our sex life through this app, and I usually try to have it as often as possible throughout the fertile window, and as much as time allows throughout the rest of the month.

However, yesterday I noticed that my period had been changed and as a result, so had my fertile window, cutting us short at the end.

I only noticed because it says we had sex on the first two days of my cycle, and we didn't.

Why does this happen?

Thank you!
