Need support! ?

I'm having a terrible time. I'm 5 weeks and  2 weeks now I've been having horrible cramping. Saw the dr and she  said nothing is wrong, i do have a fibroid, but its fine. I'm so exhausted, I am up all night with terrible cramps, then get up at 5:30 for work, I'm a teacher. Work all day with cramps. I feel like I'm being tortured. I don't want to be pregnant anymore. I'm in pain non stop, nothing helps. I'm always tired because I can't sleep and alwYs in pain. Im just so over this.
