Help, first pregnancy.

Hi, I’m a first time Mom so I really don’t know 😂. But I have been having What a think are contractions off and on since about 3 am last night. I was laying down and my stomach would tighten then I would get like a mild period pain at the bottom close to my cervix. I tracked them and they were for 25-30 seconds and 5 mins apart. I moved position and they stopped then when I woke up they started back up again. I sat on the couch and they started back up Same time and length. And now they are coming irregularly. I don’t want to just call my doctor if it could be nothing. So I guess I’m just looking for some advice on what I should do. Thanks 😊
