No discharge

So my period is in two days and ever since my fertile I have had no discharge, I have had "banana free" sex i.e. oral being fingered and oral but I'm afraid that a mistake may have been made and there is a chance that I am pregnant. Am I just being crazy? 
(Side note: it's been ten days since the sex took place and there has been no spotting at all, I'm fairly sure I'm just paranoid I just need to calm my nerves)
Update: period came right on schedule, also Raissa; you the real mvp
