Really frustrated...

Okay. So for starters, last month my period was super late and before my period was even supposed to come, my boobs were really sensitive, I had almost every symptom there was of being pregnant.. Then I started my period.

This month, on the day I was supposed to start my period, there was little blood, and thought it was starting. (It usually does come out slowly/ but only does it for a day or 2).. This went on for a few days.then almost no blood every day after . the blood started the 23rd. So at this point I kinda think I'm pregnant.. But today, I started feeling little cramping here and there, but not like period camping, lighter.. And just now I went to the bathroom and there was blood. It was dark and stringy like.. But not heavy. I'm so frustrated .. This never ever happens and for something different to happen the past 2 months is just getting my mind going. I haven't been to the doctor yet because I don't have insurance (I'm going tomorrow to sign up, but who knows he long that'll take..) If anyone has experienced anything like this please give me some opinions!
