Need Advice!

Haven
Hi. I'm Haven, I don't really know when my cycle is suppose to begin, mainly because I haven't stopped bleeding since January 2. I'll bleed every other day and go a week without and start a new period and then it's back to every other day. I went another 4 days without bleeding early February, and I'm back to bleeding again. I didn't bleed the 15th or the 16th and I've been spotting since. My periods are kind of irregular, obviously, i have unconfirmed PCOS and it's hard to track ovulation but I started charting my BBT today and I took my first OPK yesterday just seeing what it said. I have aboutttt 6 apps I'm using and they are all saying the same thing so my predicted cycle date is February 26 but yah know how that goes sadly :(  Any advice would be greatly appreciated as well. I had a miscarriage in September , had a off period October and November and had a regular cycle in December and now it's down to this.
