Waiting sucks...

So I know I said I was going to test tomorrow but instead I'm going to wait one more week only because I ran into one of the assistants at my drs and she said I think you should take a test in a week if you havent started your period by then...I told her (yesterday) that I was 6 days late (now 7 days late today) that I could be anywhere between 1-3 weeks pregnant and she said the earlier in pregnancy the more faint the second line will be to where when you're at least 4-6 weeks pregnant the second line is a little bit more visible and not so faint so I'm taking her up on her advice and waiting another week to test but I just have a feeling that I might be pregnant I feel nauseous tired all the smell just about everything I'm moody I'm always hungry constant headaches and lower back aches and now starting to have heartburn. My husband and I did the pull out method 3x Sept 21st 28th and Oct 6th and then he came inside me on the Oct 10th and I'm now 7 days late on my period...feel free to comment you thoughts or advice or even if you sending some baby dust I appreciate all comments just no negativity thank you
