super bloated 👎🏻

My period is super irregular because of the birth control that I'm on and I almost never get it. In March I had sex without a condom but I got my period at the end of April for a full 6 days. This was my first period in 7 months. 2 days after that period ended I was worried I messed up my birth control so just to be careful I took a plan B. A week after taking plan B I got another period for 5 days. Lately I've been super bloated and I think it's just a side effect from the plan B but I'm worried I could be pregnant! I had 2 full periods so I highly doubt that I am but this bloating is making me look and feel horrible 😩 Any suggestions girlies?
