Bleeding before positive tests

N

I ovulated on 13 Aug and conceived.

The tests were negative whole time, until I got bleeding on my period “time”, which I thought naturally were my period. I also did one test in the bleeding time that ALSO showed negative… thus thinking i am out for the month.

This morning I had very light spotting… and I wanted to start testing with my ovulation strips again and tried again… and had a feeling to do pregnancy test… and these pop ups…

I did blood test - waiting for the results….

Did any of you experience bleeding and still be pregnant?
