Best of luck!! It could be a missed period, or you could be pregnant! I agree that a doctor's visit is in order. Did you do your HPTs first thing in the morning?
I agree. It's time to see the doctor. I hope you are pregnant! It's best to find out earlier rather than later I think. So make the appointment soon. Perhaps you could use a little help with progesterone or something to get to a different outcome than you had before. Only the Dr. can tell you that. I'm very hopeful for you.
I third that. No extra advice to give, but I wish you luck.
I agree - have the doctor do a beta on you (blood pregnancy) test. That should show conclusively whether you're pregnant or not. Even though your symptoms suggest pregnancy, it very well might be credited to a hormonal imbalance, some kind of virus, etc. In other words, it's very difficult to rely on symptoms to determine pregnancy - almost impossible.
You can have your Dr. do a blood test. When was the last time you tested? I have heard that sometimes it can take up to two weeks after missed AF to show on a test. Also sometimes we just skip a cycle for no apparent reason. Have you been under any stress? You may have O'd late. Good luck!
