Was it a chemical pregnancy?

So I am currently going on 6 months pp and my husband and I decided to try for baby #2. My cycles are normally 23/24 days long. Will after I missed my period I decided to test and to my surprise I had a faint line just like I did with with my first pregnancy. So I tested again a few hours later and it was still faint. Later that evening I didn’t feel well so I we t to the bathroom and I noticed bright pink spotting. By the time the night hit I was bleeding a little heavier than normal. I’m on day 3 and still have the heavy bleeding, cramps and really bad back pain. Was this a chemical pregnancy?
