Okay so three days ago I was supposed to get my period and it still hasn't come! I took one test a week ago and saw a faint line and took another one two days later and got a negative. I think it was negative due to the fact that I drank coffee right before. I've been getting cramps that feel like I started but nothing and that's never happened to me before, I only get cramps when my period actually starts. Do you think I could be pregnant?! We've been trying for a year!!
