First off I'm on the pills but I don't take them on time, so about two weeks ago I had sex with a condom on and tthen I had sex again early Friday morning a week after the first with a condom but then Sunday I started my period but it's not a normal period it doesn't fill up a tampon/pad this morning I was really sick and kept running back and forth to the restroom but I didn't vomit.. and my nipples are really sore.. forgot to mention I just had my period a week before I had sex the first time and they are regular so it wasn't time for another yet.. could I possibly be pregnant?

The pill is designed to be taken at the same time every day. Failure to do so increases your chance of conception. Condoms have a higher failure rate than the average person realizes.

If you do not want to become a mother, either use multiple forms of birth control correctly, or refrain from risky behavior.

You had sex, so yes, you have a chance of being pregnant. You will now have to wait to see if your next period comes as expected before testing.

Condoms have a 3 to 18 percent failure rate. The pill is less and less effective the longer do not take them regular. So yes it is very possible that pregnancy has happened. If period time comes and you miss the period, wait two weeks and then test
