Feeling confused

Been feeling very not myself lately and I dont know what's wrong. Period ended 10/4 and my ovulation ends in 1 day. But I've been feeling very tired and very emotion at the strangest things. Also around midnight to 1 am I feel like puking at times. But for about a week I've been feeling very dizzy and had headaches also.

I fell asleep on he couch friday night and my man tried to wake me up but I was out. But then I felt him put the pillow under my head and I woke up but out of no were I started crying. I haven't been woken up n cried like that since I was 12 and sick. What's wrong with me.
