Period is late, pregnancy symptoms, two negative HPT's
I am 28 years old and have been on the pill for 10 years. I went off the pill in December because my husband and I wanted to start trying for a baby. The 1st day of my LMP was Dec 10th. I am 36 days into my cycle and still no period. I don't have any of my normal premenstrual symptoms (bloating, sore breasts, heavy cramps). I started having some other symptoms such as frequent urination, nausea, loss of appetite, fullness in my breasts (but no soreness), a feeling of fullness in the pelvic area, light cramping, and heavy whitish discharge. I took a HPT at 33 days and was sure it would be positive. It was not. I continued to have all these symptoms so I took another test yesterday (day 35). Still negative. Is it possible that I'm pregnant and it's not showing up on the tests yet? I feel SO completely pregnant. Am I just psyching myself out with wishful thinking?
Thanks!
