2 MC and possibly 3rd

My HCG numbers have been low and I'm going in today to get an US to confirm whether my pregnancy is viable. According to the doc and nurse, most likely it won't be.  If so then I'll have to take meds to expel whatever is inside me. I've had a DNC previously and just a natural passing. I'm devastated to say the least that I have to go through this 3rd time around. I'm so tired, angry, upset and conflicted.
