HELP...PCOS..

Hey ladies. Tmi.. so I had sporting for a whole week before my period, had my period very light for 5 days. I have had stopping for three days now and today it was like if I had a period. It comes and goes. So basically I have been bleeding for about 3 weeks. I have PCOS I have been having normal periods since July (which was mirical for me,I had a polyp removed doc said that could be causing the bleeding, I changed my diet) but now it happening again. Has this happened to anyone? We have been trying for almost year. Any help. I really don't want to get back on birth control. It has been hard getting back on eating plan, still in that holiday mode, it feels like I have been having more bad meals than good ines. Maybe that's it. Anything helps please!
