You've had only one period since the baby was born, so it's hard to know what "regular" is. You stopped breastfeeding so that's another adjustment. Your body is still readjusting. Just because you came back after pregnancy #1 and were regular does not mean it will happen that way this time. So there is no way you can know if you are actually "late" or not. There's no magic formula for starting periods and ovulation and timing after a pregnancy or nursing stint.
I'm not sure when you say "we do not use birth control" if you mean you are using no contraception at all, or if you are referring to anything with a chemical component that could be affecting your cycles. If you are using nothing at all, then of course you have to allow a much greater chance to pregnancy, with or without the nursing factor. But you know that which is why you took a pregnancy test.
Given all that, I'd say that, other than the anxiety, there's no particularly reason to rush to your doctor. The cramping could mean any number of things. But you are not having any major symptoms of any problems, I think you just wait. I know that's frustrating. And I wouldn't spend a ton of money taking a test every few days. It's just going to frustrate you more.
Good luck and I hope you get answers soon.
