Help!

So me and my boufriend had sex 2 days before my period was gonna start. When he took the condom off hes not sure if he got some on his fingers but he forgot to wash his hands. Well like an hour later he fingered me. I was supposed to start my peruid on the 18th And it feels like i have my period now but im not bleeding! I have cramps and im bloated but nothings coming out. And im freaking out.
