Honestly, I am in the same boat as you. My last period was may 6. I was to get my next one on June 2. I still haven't gotten it. All the tests I have taken are negative. I feel different sypmtoms and know they aren't in my head! I started cramping last week like it was my period but no bleeding or spotting. I am always so tired and have had so many headaches. I felt sick yesterday and this morning. I really feel like I am going crazy. I am just hoping I ovulated late and that I will get a BFP in a few days. I set up a dr appt for Friday for a blood test. Hopefully that will put my mind at ease. Maybe you should have a blood test done as well. Best of luck!!!
Sounds very promising to me that you are pg.
