Did I make a mistake?

I'm on combo pill for 2 months already, only last week I finally had intercourse since taking it and in a brief of the moment my partner didn't pull out. I take my pills everyday nearly perfectly to minutes, the longest delay I had are between 1 hour up to 3 which only happened maybe once on the first week of dosing this blister. I take them nearly at the same time, never took it after the 12 hour window. Most of the days I take them within minutes cause I'm at work and can just quickly take them, just after my alarm rings. Never missed a pill. Didn't vomit or have severe diarrhea. Didn't take medications that could interfere. But I am so paranoid rn. My stress is literally making symptoms that are driving me crazy. I know these wouldn't be pregnancy symptoms, not after 3 days since the situation. I regret doing it without the condom. I know the only way to know for sure is to test after 2 weeks but I am so terrified whether I was dosing perfectly or not. I don't have access to abortion so that literally drives me sleepless, I cannot eat even from stress, worrying all the time about my stomach and the tension I'm feeling. I read so much different opinions here and got scared that I should have used condoms as well. Please, how possibly is it for me that something could happen? I think there was no factor that could affect the pill but I just don't know, I'm so scared that they failed.
