So i have actually been having VERY irregular periods for the past 3 years now but this is when it actually matters because my husband and i do eventually want to have our family grow. im 20 years old with a history of having cysts on my ovaries which went away in time. anyways.. my period in february went from the 16th till march 8th... almost 3 weeks straight of bleeding. and then i got my period again on march 25th. it says since i have a 37 day cycle that my ovulation days should start on the 14th.. but is that normal to bleed for 3 weeks and then apparently ovulate literally a few days later? any help would be amazing. i have been searching for answers for quite some time and im starting to worry about infertility.
