20 weeks and experiencing stomach aches/cramps

Jade
Since last night I've had a stomach cramps. They've been on off during the whole day. I'm not in excruciating pain but they are annoying aches. I'm not sure if it's RLP because I normally get that when I sneeze and that's a sharp shooting pain that lasts for a second. I've been to the toilet and that's not seemed to help. Is this normal?
