chances of pregnancy?

Had ovulation on cycle day 14 and cervix was low after... now on cycle day 21 and cervix has gone up and almost hidden? My walls feel swollen too? Not due af for another 11 days... my temp is rising daily and I'm not ill.. I feel like I want to sleep all the time and my belly is making gurgling/ rumbling sounds even though not hungry? Cm is really watery and having headaches and nausea on and off.. any ideas??
