Serious need of help.

So flipped out at the hints I'm even giving him, I told him I missed my pill and he flipped because we've have sex several times this week and this week was my ovulation week, and he did pull out but I'm experiencing all symptoms I never had any period symptoms at all before so I'm worried that that's not what it is espically since it's not due for another 2 weeks. What do I tell him? Would I want him to know before or after.
