Hello! I have irregular menstrual cycle.. sometimes I get my period after 28 days 30 days or even 35. so its really hard for me to track when im most fertile and or ovulating. First day of my last period was on June 7 and I had relationship with my partner on the 24th without condom. I have consulted several ovulation apps but they all give different dates of fertile window. So i took levo 1.5mg on June 25th evening. Will it stilk work? thanks
