AF due 9/21

We lost our first baby in May when I was 4 months pregnant and this is our first month trying to conceive again. I saw two rainbows this week! I'm praying that it was a sign. I've been feeling nauseous and have had a heightened sense of smell. I've had light cramping on and off and mild breast aches on and off. I don't know how I'm going to wait another week to test! Also I might drive my husband crazy in the meantime wondering about every little symptom ;) is anyone else in the same boat? When will you test?
