Help me!!

Ik this is so weird but I have

• been getting bad stomach cramps

• feeling like I need to poop all the time

• top and lower back hurting

I got off of birth control on January 9 it was the bar in my arm and on January 26 me and my boyfriend did stuff so it’s already been a week since we did stuff is it a possibility that those are pregnancy symptoms I know it’s too early to tell but I just need to know please
