So I had sex February 18th. At first it was protected then we just stopped using a condom. My period came a day or 2 later. I went threw the weekly period like normal but now I feel like I'm full all the time. My stomach feels bloated from morning to night as if I ate a huge meal. Half the time I wouldn't eat anything and I still feel full. I get car sick fast, I'm sensitive to smells now, and I get a sick feeling once in a while and I'm ALWAYS HUNGRY. I don't think I'm pregnant, but idk cause I never had a baby. Am I over thinking it or is there a possibility? Help!
