22 yr old, 19 months TTC :'(

My fiancé and I have been TTC for almost 2 years with no luck at all, my ovulation cycle is very irregular I got 16 periods last year most 2-3 days, a couple 8-9 days long :( mostly light flow but very painful. I can only remember maybe half the months having heavy EWCM for possible chances to finally conceive but still ending up having my period the next month. I had a cyst burst in October and then noticed regular ovulating. But I still end up with AF. Has anyone else had so many fertility problems this young? :(
