Pregnancy or PMS?

Okay. I have posted some similar questions before but have some new developments. I am on my third cycle of Clomid. 50mg the first month, did not ovulate, 100mg the second month, did not ovulate and now this month I took 150mg of clomid and ovulated. My day 21 progesterone level the first month was 1.4, 2nd month 1.6 and this month 8.8. I am now on cycle day 28 and have had the following symptoms for the past week: severly sore with a few days of being raw, frequent urination off and on, exhaustion off and on, low mestrual cramps and bloating, and a canker sore in my mouth. I was sure that I was either pregnant or going to start my period or that I was pregnant but all the HPT are neg. I went today for a blood test. I havent gotten my period yet. This is not out of the ordinary for me since I have PCOS and usually take Provera to have a period. This time was just different in that 1. I ovulated and 2. I have all these symptoms that I have never experienced before.
