am I preganant?

me and my boyfriend had sex December 29th and he came inside me, I found out later that night that I was ovulating... I have the birth control implant and have had it for a little over a year now. he's came inside me multiple times, sometimes even when I was on my period. I have recently been eating non stop, and having a lot of emotional problems. my periods are very irregular so I never know when to expect them.
