Can I Get Insurance After the ObamaCare Deadline?

I came back from Iraq in 10/14 as I was working there as a contractor. I found 2 part time jobs in December 2014 and have been working without insurance. I was going to get the Obamacare insurance last week, but did not since one of my jobs told me that I will not have the same scheduled days as before. Missed the deadline for signing up, and now my hours are less and need to get insurance for my family. How can I enroll to get insurance thru Obama Care? Please help.
