I believe I'm around 6 dpo. Up until now, I have been keeping an eye out for any and all symptoms I have been having, which haven't been many! AF isn't due until about 2/3. Today I have been having some killer cramps. They feel like AF cramps but with a little more kick to them (especially on my right side). I know 6 dpo is pretty early to be taking a test, but what is the earliest I should try?
