Period duration is only 2 days

I went of the pill 5 months ago. Before I started to use the pill a few years ago my period was 5days long, now it is 2 days. My cycle was 28 days, now it is 25-26 days. My skin started to break out this month. We want to start ttc in April and I was hoping that my hormones would have gone back to normal by now. Do you think that I would be able to become pregnant with my cycle all messed up? I am 33 years old.
