Chemical pregnancy?

Kara • 28. TTC 1st baby! Step-mother to 👦🏼👦🏼👦🏼. Have 5 fur babies 🐕🐕🐕🐈🐈.

Hey ladies! My husband and I have been ttc for a year now with no luck thus far. I’m just wondering if there are any distinguishing signs/symptoms of a chemical pregnancy? I was due for my period to start yesterday but two days ago I started bleeding very very heavily and is still happening. It is also followed with severe cramps and in my opinion an abnormal amount of blood clots. Is this just my period or a possible chemical pregnancy?
