Feel guilty that I ended up in the ER

Yesterday morning I woke up with sharp pains on my right lower pelvis. I went to work and the sharp pain would come a go. By 12pm it really hadn't subsidized so I call my ONGYN. Since I knew it wasn't cramps and I wasn't bleeding they told me to head to the ER in case it was a cyst or Appendicitis. So I head to the ER. They took me directly to labor and Delivery and put me on a fetal monitor to make sure I wasn't contracting. I looked good so they sent us back down to the ER for nonbaby work up. Long story short. 2 ultrasounds and 1 MRI (which my baby did not like) they ruled out appendicitis and ovary issues. They noticed the baby favored my right side and told me it was just rounding ligament pain. This is my third child. I feel so guilty that I went to the ER for normal growing pains. We are insured, but it will still be expensive with all those test. I feel guilty my poor husband missed work and didn't eat til we got home 12 hours later. I feel guilty that I missed work seeing they just hired me and we have an event on Saturday I need to prep for. I feel guilty that I am working from home today. Then I feel guilty that I am feeling guilty when I know it was the right thing to do. Maybe I am embarrassed that I got worked up for a normal part of pregnancy. Am I just being crazy?
