Wtf is going on

Ok so this might be a lot but ill try to summarize. So basically, i weaned my 2 year old at the end of may. Had a late period by almost a week and a half. My cycle became pretty long while bf. I was usually several days late. Well middle of last week i developed a yeast infection. Havent had one of those since like 2017... Got monistat 3. Started having some spotting after finishing it. Now today its almost like a full blown period is starting and its not due for like another week and a half. Should i be concerned? Is this from weaning? Idk what to think. No other symptoms besides cramping.
