Experiences of cycles going funny after giving birth

Hey, I gave birth November 7th(nearly 5 months ago). Didn't breast feed for long so that isn't affecting my cycle.

I didn't get a normal period til January, even had ewcm so I know I ovulated and then got my period 14 days later,which is my normal lp. (normal 28 day cycle)

February no sign of ovulation (no ewcm) and my cycle was 24 days(period came early)

Now in March didn't get any signs of ovulation again and my cycle is on day 39 and still no af, took a test yesterday and was negative.

I've had pregnancy symptoms for two weeks apart from last few days they seem to have disappeared. I really don't know what is going on with my body.( I've had unprotected sex durout March)

Was hoping someone could share this their experience of their cycles after giving birth. So I know if it's normal or not.
