Shorter cycles while TTC

Tiffany • 34, first pregnancy due 5/8/20

Has anyone started getting shorter cycles when they were TTC?

My cycles have been methodically regular at 28 days with no birth control. Since we started TTC (and this is our 5th month), I’ve been getting shorter cycles, ranging from 25-27 days, with one actually being longer at 31days. Curious if that means we’re just getting close to conceiving? 😬
