Cramps throughout pregnancy

La

At the beginning of my pregnancy I had tons of light cramps, very consistently. After week 8 they stopped and hardly fell anything. Now I'm at week 12 and they started again. They are very light period-like cramps mixed with what I do think it's similar to a tingling sensation from the inside. All in my very low tummy (DEF not gas). Did you or do you feel this? Do you guys get cramps throughout the second trimester too? I guess it's everything expanding and it's too early to feel the baby but it's so different. No blood at all so I'm not worried. But curious!
