Anyone suffered a chemical?

Rebecca • 27, TTC my second baby. I love my husband for giving me baby #1 who is the most amazing gift in the world!!
Ok so I was getting faint positive tests on different brands and then I started bleeding so I assume I've had a chemical pregnancy :-( I was absolutely devastated and still am. Saturday I thought I had implantation bleeding as I had pink tinged cm but only happened 3 times when I wiped. Sunday was basically spotting only when I wiped it stained the tp. Monday I had dark red heavy bleeding with tiny clots like the tip of a pen but still not relatively heavy for my usual period it didn't even fill a pad it was just when I wiped. Tuesday went back to spotting and stopped. I had sex that night and Wednesday morning I had spotting until dinner time it's gone now. I'm still getting that feeling that I'm pregnant and I'm getting really bad bouts of heartburn which is making me feel sick which I only experienced when I was pregnant with ds1 I know I can't be pregnant because of the bleeding but my question is how long will it take the pregnancy symptoms to go away? I had these symptoms when I was getting the faint positives and I thought they would go away when I started bleeding, the exhaustion and heartburn is turning me into a moody cow!
