Am I possibly pregnant?

Hi everyone. I am freaking myself out (maybe?). So, I have been taking birth control pills for just over a year now. Well this time, my period was much shorter than normal and I didn’t take my birth control until I was supposed to stop. Well, when I tracked this past short period, it ended up going into the medium chance of pregnancy and my husband and I have had sex (no protection) since I ended early (newly weds). But now I am having a lot of discharge and when my husband and I had intercourse last night I started bleeding a lot. I started birth control as soon as I realized I was in the medium chance of getting pregnant. But I am freaking myself out now. I am still in school and I am not ready to be a mom. Anyone have any advice?
