Am I pregnant or just crazy?

Okay so my boyfriend came inside me quite a few times a few weeks ago, and I’m starting to notice some different things going on. I’ve been having headaches everyday, hunger pains as soon as I wake up, I’ve been gassy, my feet ankles and hands have been swollen, I’ve been bloated, having some weird cramps, I ate some vanilla ice cream the other day and wanted to puke it tasted horrible and I’ve also been craving certain foods. Help!
