I don't have them anymore but, earlier, I had some Taco Bell, I had a crunch wrap, it was pretty big, a little bit after, in my upper stomach, right below my boobs, it felt like I was having period like cramps. I'm not sure if it was heart burn, or I was having light/mild contractions. I'm super SUPER early, I am 6 weeks, and 6 days pregnant, pretty much 7 weeks... Is this normal?
