Confused!

Nikki
My last period on birth control was July 4. I had the break through bleeding on July 15ish...I then got a normal period on August 10...my period was due on September 7, but I am 1 week late today. According to my period calculator I would be 5 weeks, today. All of my urine tests are negative . I went in for a blood test on Saturday which was negative also. This is so confusing to me because my stomach is so bloated & im so hungry & tired..I also have been cramping every now and then. (Sorry for tmi, but my cervix is covered in the white discharge & when I'm about to start my period, I am dry). Maybe monthly Martha is just going to be extremely mean this month..I'm not sure! But I can honestly say that I wish she would show so I can ttc again.... Has anyone had this issue and ended up being pregnant or should I just patiently wait for Martha!?
