Question

Alright guys my mom got pregnant with me when she was on birth control and sick at the same time. 
I'm not on birth control but I have a bad viral infection and I'm running a high fever and feeling sick at my stomach. 
My boyfriend and I had unprotected sex the past two days while I was sick and didn't pull out because of the heat of the moment. 
Is that a easy way to get pregnant too.?
I'm not so much stressed about it as I am upset because he leaves for basic training in January and won't return for ten months.. 
Should I stay calm and not worry or see a doctor in the next few weeks.?
