Hello. I Had A Miscarriage On Tuesday Night. I Was

Hello. I had a miscarriage on Tuesday night. I was four weeks and three days pregnant. I saw the bag come out the tissue as I wiped. Is it possible for me to still be pregnant? I think my body aborted one of the babies and I am still currently pregnant with another one. I know this may sound crazy but now I am experiencing morning sickness, tenderness of the breast and weird cravings. This has happened to me once so is it possible for it to happen again? Or did I get pregnant right after I lost the baby since I had unprotected sex. I did not go to the doctor after the miscarriage because I feel that I am still pregnant. I want to go to the doctor when it is time for me to have a sonogram so that we can talk. Can you please help me?
