Sorry for the long post

Has anyone previously or currently had positive tests but had what u believed to be AF? Long story short is I had a mc back in October, had a normal period 27th November 2020, got a positive on clear blue on 31st Dec then bled on 2nd Jan (much lighter and shorter than my usual cycle, 3-4 days instead of 5-6). Thought nothing of it, got a positive on a clear blue again on 28th Jan and 31st Jan with fmu, started to spot on 2nd Feb at 7pm n by 7pm last night (4th Feb) I had nothing which makes it only 48hrs again. My cycle was knly 31 days as well compared to my usual 36-40day cycle. I've contacted gp but just wondered if anybody else had any 1st hand experience xx
