I've been late just for 3 days. And i took a test, its positive. Am i pregnant?

But i feel pain on my stomach, and i have a backache too. And i feel aches all over my body. So i dont know if its okay?

I plan to go to the doctor but my husband has a schedule today, is it okay too if i go to the doctor later?
