My heart hurts

Michelle • I`m 24 baby Declan arrived 08/07/2017! I have 3 angel babies.06/18/15 and mono-mono twins on 06/27/16.
After finding out last week that I was pregnant with twins but one did not make it and the other had a low heart beat (97) I found out yesterday I'm  having another miscarriage. Last year around this time I had a missed miscarriage and had a DNC June 30th due to the pills not working. Now I'm going through the same thing again. I measured fine June 10th had a yolk sac but no fetal pole but I was 5 weeks and 5 or 6 days based in the ges sac measurements and it matched with my last period. June 23rd I should have been 7 weeks 6 but there were 2 yolks this time and I measured 5 weeks 6 days. I went back yesterday June 29th I should have been 8 weeks 5 days but I measured 6 weeks even and no heartbeat and only the other was completely gone. It looks like I'm having another missed miscarriage I'm not spotting or cramping. I just wonder what is wrong with me to miscarriage and second time? I have no children and this hurts so much. I feel like my body has failed me. This time it's not as bad I knew it was going to happen again. And I've gone through it before. Friday I go discuss my options. Which I know what they are DNC or the pills they will discuss my weight and my birth control options. Now it's just time to fake a smile and go with the flow and it will all be over before I know it.
