birth control

Hey guys so I got my period Thursday July 16th around night time and I started birth control on Monday (july 20th) . I’m taking Drospirenone and Ethinyl Estradiol Tablet. I’m still bleeding till this day (july 22nd) but it’s spotting and very light. I had unprotected sex in the pool today at my house it was in the water and it was a couple of strokes i would say 7? He didn’t cum in me. Am i good?
