Chemical and getting pregnant

So I had a chemical this month I found out a few days before the 4th of July then started bleeding July 5th and bled for about a week it’s been 10 days since the bleeding has stopped and me and my husband have been having unproductive sex but I have been having some serious pregnancy symptoms like I did with my daughter she is now 4 months old I’m super dizzy and light headed like I’m ganna faint super nauseous and have sore Nipples and boobs and earlier today I was laughing and crying hysterically at the same time for no reason but there’s no way I’m pregnant already right? I have no idea what’s going on 🤷🏼‍♀️
