Question

Amanda • Mommy of 3 girls Caydence Brooke 4.29.08 and Ella Tinlee 11.4.12 Arrow Finn 6.19.18. 🍼🍼💓💞😁😁

I am normally a 27 day cycle. this cycle I was 30 days. now glow is saying I'm fertile only 5 days after my period stops. that seems kinda short. do I need to just test and pin point it myself? this has thrown me off.
