I think I had a misscarriage

My period was over a week late which made me paranoid that I was pregnant .. I tried to convince myself that I am not since I've used the conform all of the time.. I was cramping very badly to the point i was short of breath.. But then the other day I started to spot which made me a little worried because from the research that I've done spotting can mean that the embryo is attaching itself to the womb so I got even more paranoid .. Then I git my period which gave me a relief at first because it meant that I wasn't .. Until I realised that my period was not the same and it had a much different texture than usual.. I've researched that too and most of my leads lead to misscarriage
