How long after an early miscarriage dose it take for af to turn up?

I miscarried 5 weeks ago and still no sign of af. Im sure all hormones are out my system as few days after mc started all symptoms was gone and pregnancy test was back to negative.

Not sure when I ovulated as I had ewcm and cramping on the 16th July then again on the 24th July.

Last few days I have been having cramping, feeling sick and now boobs are starting to hurt so confused cervix is medium and soft and cm is water like but sometimes creamy but not thick

I did a pregnancy test on the 6 Aug and it was negative. Going to test again if still no af by Friday.

Could I be pregnant or just late due to mc
