Hello, I've been crazy food cravings for the past two weeks and been nausea every morning and sometimes after I eat certain foods. I had sex on my last fertility day and my period been a day lat for the last two months. When my cycle comes on it's not heavy like it's use to. It's been VERY light (light like I dnt have to wear a tampon and pad, blood only show when I go to the restroom) and when I eat it seems like I can't get full. Am I pregnant??
