Could I get pregnant?

It's 7 days before AF and I took a clear blue easy read ovulation test in the morning and had a positive LH surge. I had sex a little while ago and he finished with me on bottom. I just stopped taking birth control 2 weeks ago. I had a positive ovulation on March 30, April 4 and today. Is there a high chance of pregnancy or is it just my birth control messing with me?
