I’m scared

My pharmacy messed up my pill for a while, they just were not filling my prescription. so I was just told to skip the rest of the month and start with my next period so I don’t mess up my cycle ( they’ve done this before). I have not been using proper birth control because I’m stupid and I know better. I’m not to the point where I’m late yet but I’m anxious. I had a dream I was pregnant and I now feel like that means something. I thought I heard somewhere that your body tells you things in dreams. I also read lots of articles to see if I was and I think it’s too early for me to know. I’m going to buy plan b and tests to calm my nerves. But I’m worried because I am so active. I think I’ve learned my lesson but I don’t know if I’m just overthinking which I tend to do a lot.
