Cervix question

Ok so my hubby wanted to get involved or more involved in the ttc stuff...so I have been askig/letting him do my cervix check before we have sex usually in the evening or night when I'm in bed. Well I am 1 day from my period have been having really odd symptoms naseua, dizziness, headache, feeling flushed, so hungry...and of course tired. No cramping. Well he said last night my cervix was medium position still soft and still open. It never closed since fertile window does this mean I am for sure getting my period and I'm out. I was pretty sure he cervix would be closed if you conceived. So that means I'm out this month right?
