Paranoid.

Hey so I am on the pill and I take it religiously everyday. A few weeks ago, my BF and I had sex. He pulled out on time, but I am still soo nervous. I recently changed BC to Yasmin because I use to spot about every 2 weeks on lo loestrin fe. But the last week before I changed pills, I didn’t bleed at all and that is why I am so stressed out about this! I just need reassurance that’s I’m okay!! Please help. I am so so nervous and scared!
