Why would my lp suddenly change?

[4cheekyboys]

Since i've been charting(since 2004) i've ALWAYS had a 14 day lp. Last cycle it was 13 and this month it was 11!!! Other then seeing a chiro for some back issues nothing has changed in my circumstances so i don't know why that would happen. I'm paranoid that it's going to make it hard to get pregnant. Anyone had a suddenly changing lp?

Hi There

Mine were usually 11, then went to 14 for two cycles, and then came back to 11. It happens. 11 is long enough to fall pg. Good luck!
