Spotting 4 days before af due... was taking progesterone after mc.. soooo frustrated...

Hi all. TTC #1. AF isn't due until sun but started spotting today. Light enough and no cramps. Totally confused. Was on progesterone for a few months after early mc in sept. It was precautionary and used to take it every month once I knew I ovulated and really think it messed up my whole body and cycles. Off it now for 3 to 4 months. Really frustrated and just don't know what to do 😐😕
