Lower back pain!

Hello ladies....I'm almost ten weeks and I'm kind of freaking. I think I read too many horror stories about miscarriages on here. Anyways I'm lower back has been killing me the last two days. I took a bath last night and it didn't help. I'm not being just a big baby lol it really hurts. I don't have any period like cramping. Just a few sharp pains every few hours. I don't have an us for another couple weeks but I'm feeling nervous. Anyone have a similar experience?
