Just Freaking Out

I woke up this morning around 9 (after the shot at 7) and went to the bathroom. There was some brownish spotting. I freaked out because not only did I have spotting, I was cramping a little bit. I told my husband and we both looked through the books I have together to see what could be causing it. There are many different reasons - both good and bad. Luckily, when I went to the bathroom a moment ago, there was no spotting, but still a bit of cramping. I told myself that if the spotting happens again, I'll call the clinic. Otherwise, I'll wait until Monday when I'm scheduled for my ultrasound. I hope everything is o.k. in there - I would really hate to get this far, then lose everything and have to start all over again.
