Could I be pregnant?

Question

My period was really late last month and only lasted a day or two. Now, this month, I haven't started. I've been more tired than usual, headaches, sore breasts, backaches....but I took a test and it came back negative. I haven't been stressed out anymore than usual, and I'm on birth control. Usually when I'm on bc my periods are really regular and heavy, but like I said, last month it was almost nonexistent and this month it still hasn't come.

Answer 1

If you have had sex, you could be pregnant as NOTHING is 100% effective except for abstinence.
