Chance of pregnancy?

ni

I’m on the pill. I usually skip the placebo pills so I have had a super long period as a result of skipping them since September. I’ve been bleeding since March 31st. Does this mean there’s no chance of me being pregnant? Or is there still a chance of me being pregnant?

My PMS symptoms are bad, so I’m a little worried that they could be pregnancy symptoms. If there’s no chance that I am pregnant though, I won’t bother with a test.

Thank you guys so much for any advice. I apologize if this is a stupid question, I was never really educated on how my cycle works.
