AF came but only for 48 hours (super super light)

We have been TTC for a year with no luck. Usually my periods are 4 days and my cycle is around 26 days. I had every sign I was going to miss AF this month. She came Tuesday morning but today she’s gone but my boobs still hurt, I’m still bloated and just feeling off. (Have not taken a HPT) Anyone else had this? Could it just be AF being weird, lack is estrogen or who knows?
