Miscarriage or never pregnant?

Hi moomies,

I am completely lost and confused. We have been TTC for number two, and I was convinced that I am pregnant.

Had all the symptoms about a week after ovulation, nausea, fatigue, sore breasts, slight cramping, headaches. Did I want to be pregnant so badly that I imagined the symptoms?

Then my period started, and the symptoms just started fading, I am having slight back pain that I never have with period and it only lasted 2 days, normally 5-6days.

Could it be possible that I had a miscarriage? Or did I just believe myself to be pregnant?

Hope you all are well.
