So this is going to sound a little crazy but I’m desperate

So according to glow I’m suppose to start my period today but about 3 days ago I had pink spotting thought period came early but I had no more bleeding after that so yesterday I had cramps nothing painful and I had a little bit of blood on the tissue so I thought that was my period starting then nothing again I go to the bathroom just now thinking I started my period but this was on the tissue any ideas?

Besides this my boobs have been slightly sore, my sleep schedule has changed a little, I’m a little more emotional (but I think that’s just PMS)
