4 weeks and I woke up with built up pain

In my stomach, kind of felt like period pains but I was super constipated. Back and forth to the washroom from 4am to 5/530am.

Then I woke up and started puking, with that same pain only very faint and still had to go poop.

Is it normal to have period like pains in early pregnancy???? Almost keep getting scared my damn period is going to start.
