nervous

I live in Maine and all week we've had a blizzard so I haven't been able to see a doctor
And when I've called no answer
I am not TTC
I am on Nexplanon and The pill (okayed by doctor) I was put on the pill to stop break through bleeding from the nexplanon 
My boyfriend and I have had unprotected sex several times 
More so a couple of weeks ago when we were being careless. 
We are being smarter now.
I know it was stupid
Recently I have noticed lots of on and off creamy discharge 
Not A LOT but enough
And it has a smell
I'm not exactly sure if I should be scared right now..
