Scared

I've taken plan b 5 months ago and got a period each month after. Can I be pregnant? Sometimes I feel my stomach move lately when I think about pregnancy could this just be gas and intestines moving ? I get gas after usually. I'm worried and I only feel off when I think about being pregs and not knowing. Sometimes I feel nauseous but not really or nothing serve. I’m prone to feeling nauseous when nervous.

He came inside of me and I took plan b the next day, got my period expected date and been getting it since. No signs or symptoms. It's been 5 months. Sometimes I feel sick but it can be anything. I took plan b in January got my period a week later when it was due, and each month got it same week first day heaviest blood next day less. My periods are 2 days

Am I ok it’s been 5 months ? I would’ve shown by now and boob size would’ve gone up? I haven’t gained any weight.
