Condoms actually work pretty well if used properly so if you didn't notice any leaking or breakage I would say it's unlikely that your pregnant. I also have a very irregular period in the same way you described. After I started having sex, every month when my period was due soon I would start stressing and worrying that I might be pregnant and I would start to get the same symptoms that you described: very light spotting when wiping and peeing a lot but I still always got my period in the end. I've heard stress can cause early pregnancy symptoms especially if your aware of what early pregnancy symptoms are. If your really worried about it then definitely take a pregnancy test soon to ease your mind if nothing else.
