Can someone help me ?

I have period like cramps on my lower abdomen but a bit different than period cramps and I am TTC . And my period is not till next month and I had my regular period this month and it was on time. I also just started bleeding today Idk if it's coming early or I'm spotting idk . It's not a miscarriage because i would think I would be bleeding more than I am. does this mean anything ? Should I take a pregnancy test ? I'm so confused
