My husband and I have been trying to conceive our first baby for over a year. We had a miscarriage very early on in the pregnancy back in April 2013. Ever since then, my periods have been regular. My period is now five days late. I was so excited that I took a First Response test when I was 2 and 4 days late, and I even took a ClearBlue today, but they all came back negative. When I found out I was pregnant last time, I was 4 days late. I have been having sore breasts, fatigue, slight cramping a few days ago which have subsided. No darkening of the aerolas, but veins on my breasts are now visibly noticeable. Should I wait a few days and try another test?? And if so and that one still comes back negative, how long should I wait before I call the doctor?? Any help would be greatly appreciated!!!!
