Ok I need some advice please. Before dd which was 4 years ago, I was not very regular, then after dd I was. Now my new dh and I have been trying to conceive. With being very regular, last month my cycle was barely 2 days, now this month I am 4 days late. Have taken multiple tests, but each have been negative. Any suggestions? Pregnant or not? How long should I wait for a positive? Thanks ahead of time.
