Help me??

I'm TTC. I have PCOS so my periods had been irreuglar until i started BC. Was on that for a year with reg periods. Stopped BC in January. Periods stayed reg. Last period was middle ish of Sept. Roughly 14 days late. Had numerous preg symptoms (sore breasts, cramping, spotting around when my period should have been, peeing more, nausea spells and mkst recently discomfort in stomach, and almost a blood like taste) taken a few tests before some faint lines and some neg. Took one yesterday on SMU and this popped up within the time frame and stayed. Plllease help. I am hoping its legit
