I been having cramps since when I believe I have ovulated and I did have sex and I stopped my birth control as of my last period and I been eating in weird ways like not eating for like three days but i did force myself to eat at least one meal then eating everything in sight the next and been having headaches bad enough of seeing spots,heavy like lotion discharge no odor through. Any ideas if it could be it and I'm pregnant or just making it up in my head
