Getting anxious, need some input :)

So I had a diagnose MC 7w2d the day of my US it died they said that morning or the night before July 12th but it took 21 days for my body to release the "products of conception" (easier for me than the other word, nothing personal!) during those 21 days I had 2 more ultrasounds to check on it because it was taking so long for me to bleed and then my dr told me July 31st if I don't start bleeding to call the office and head to the ER on Monday, I started bleeding at 1am on Friday night/Saturday morning, and I did end up in the ER and need to have the placenta removed from my cervix cuz it was stuck so they just pulled it out gently, to stop my body from bleeding out, and as soon as they removed the placenta there was a big decrease in the pain. I had to stay over night cuz I needed a blood transfusion and some more blood tests, and my blood test the next morning showed I had less than 5 whatever that is in my blood for pregnancy so I wasn't pregnant anymore, we waited a cycle like told to and then last cycle we didn't get pregnant and this cycle I'm currently 7DPO and right now I feel like I'm out even though I'm having some pinchin and twinges and stuff, but could the MC taking so long to release be the reason I'm not pregnant yet? We got pregnant the first cycle I stopped BCP in April.
