pregnancy journey

Hi! My new husband and I are starting to try and get pregnant and I was wondering what are some weird signs that everyone got that maybe we’re early signs of pregnancy? I had a period a week ago, and now i’m getting some small stomachaches and I’m a little constipated and gassy. It could be because we went out of town for the weekend and my stomach is weird anyway, but I don’t want to just take pregnancy tests constantly so I don’t know I was just wondering if this would be something to take a test for?
