I need advice....?

I am on cycle day 21 and I have 7 days to go. I am watching every twinge. I did not notice any ewcm, however, lately within the last day or so I have had an over abundance of creamy cm. My temp this morning was 98.1 and it has been up for about a week now staying between 97.7-98.1. we bd'd on cycle days: 3,5,7,9,11,14, 17,20. I have had strange cravings and an increased appetite, sore and i have taken cranky to a new level and i am so emotional, nausea, heartburn. would i be experiencing any signs now or is it all in the mind. Also, for the last two months my cycle on lasted 2 days and then it was gone. I think that could be due to the increased amount of that we are having trying to create our love child. opinions, advice and intelligent thoughts are welcomed.
