Can pregnant women have a mole removed while pregnant?

I had a small mole removed from my armpit at 15 1/2 weeks. The doc used a small amount of lidocaine to numb, then cut and lastly cauterized it. I'm kind of freaking out about the cauterizing part due to the machines ability in sending out electric currents. Long story short, about 5 hours after procedure I began to have mild cramping which intensified the following day. I left work and went to the hospital due to the uneasy feeling of pain. I called out the following day as well due to pain.
