Omg!! Im past the fertile days

Omg!! Im past the fertile days on my glow calendar today Thursday 4th was not suppose to be a fertile day according to glow. Iv been doing more things to track my cycles i seem to be 30 days with 3 day long period but it can be hard to tell since they are light. I got target cheap brand ovulation sticks and started testing during the green days glow has on my calendar but nothing was showing more positive even on the most fertile day! Anyways im still testing today Thursday 4th which isnt suppose to be fertile anymore but when i tested strips came out postive!! I checked my cm and position and all the other days i could reach it this time its further away but i can still feel it. Its soft, still moist and i would say feels like lips and open. Im really thinking iv been following glows calendar for 2 months and other predicted calendars after those days i would stop having as much sex and relax and see what happends. I do belive iv been missing my days. What do you think?!!
