Thoughts?

Ok so before I start let me say I do have an appointment in the morning. So 2 weeks ago I went in for a follow up appointment after some light spotting that went on for a week. All was well except my baby measured 5+5 when they should’ve measured 7+1. My dr wasn’t concerned because we saw a confirmed heartbeat. HOURS and I mean 2 hours after my appointment I began to cramp horribly and bleed. I passed a few large clots and decided to go to the ER. Well after an US they said they couldnt find the baby. Now this is the same ER that “couldn’t” find my baby the week before. Now 2 weeks after they “diagnosed” me with going through a miscarriage. I still have my symptoms which before you say it I know some women still have them BUT I have symptoms I didn’t even have when I was pregnant. Last week I developed morning sickness and it was so bad I was gagging at certain smells. My face which never breaks out (well until I got pregnant or occasionally on my period) is getting acne. I still have aches and pains. And I also didn’t get headaches before I got pregnant and I had a terrible one this morning. So I thought I’d get another opinion. Could I have been “misdiagnosed” and still be pregnant or is this just the effects of the miscarriage?
