ttc and confused

This is month four of ttc for baby #3. I could have sworn this month was our month but a day before my period was due af showed. I’m confused because normally I have heavy, long, painful periods but this month It was 4 days of very very light bleeding. All hpt are negative and opks have been dark or close to positive since cd20 (od’ed cd17)

I don’t know what is going and I keep telling myself just to wait but it doesn’t work

Any similar stories? What happened?
