HELP!!

Lexi • One ectopic. One miscarriage.

We have been TTC and have started clomid. Quick back story, I had an ectopic July 2016 and my right tube was removed. We did clomid this round again, and I ovulated last Monday. My left side is cramping so bad today and only getting worse. I don't know if I should head straight to the dr? As I don't think they would be able to tell if I'm pregnant even with an HCG test this early. Help!!??
