I took my birth control that day but not at the normal time I take it, but I have been having light bleeding mild cramping and cramping when I have a bowel movement its been going on for about 13 days now and I am not due for my period till June 4th What is going on?? Am I pregnant??

When you are inconsistent with birth control, it can certainly increase the risk of conception.

Since you aren't yet due for your period, I would advise you to try not to stress out as that can affect when your period arrives. If you don't menstruate, you can take a home pregnancy test. Until then, all we can do is postulate but none of that will give you an actual answer.

No form of birth control is 100 percent, there are 1000's of babies born every year from people who just used "pills"

But till your period is due and late there is nothing you can do but wait

If your old enough to spread them, your old enough to accept the responsibilities.
