Hpt really dark second line at 14dpo/4weeks

Al
I've read that a really dark line on he pregnancy test this early can be an indication of twins. Is this true? I know for a fact that I ovulated on November 5, I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> on that day. I've gotten a BFP on 11dpo/<a href="https://glowing.com/glow-fertility-program">IUI</a> and today is 14dpo/<a href="https://glowing.com/glow-fertility-program">IUI</a> and the line is almost darker than the control. I will get my beta numbers tomorrow (doctor confirmed pregnancy, but ordered two more tests to monitor the numbers). Any thoughts?
