Period or no period.. pregnant?🌸 please help..

This is so confusing πŸ€¦β€β™€οΈ But i had my period in Aug.. it ended at around the 2nd.. according to myself I had to ovulate at around the 11th and then my period would start again at around the 25th. I dont ever have irregular periods and I go for checkups 🌸

But .. my SO and I had intercourse the DAY before my Ovulation and usef no form of birth control.

The confusing part is that I HAD to start mt period on the 25th of Aug... but I kinda already HAD IT around the 19th!πŸ€¦β€β™€οΈπŸ€”

And my period (that i had to have around the 25th ) still isnt here!πŸ€¦β€β™€οΈ

Should I still test. Was the period that I thought was a period maybe NOT a period??πŸ€”πŸŒΈ

Please help!🌸🌼
