Just got my BFP

Just got my BFP. I can't help but cry tears of joy. I woke my husband up and he was also ecstatic. I've had creamy CM for the pst week so I didn't think I could be pregnant based on my research. Last night I had absolutely terrible gas pains. So severe I was healing over in pain. Someone said it could mean I'm pregnant. I didn't think that was a early sign, but I hadn't eaten anything out of the ordinary. So I tested this morning and BOOM! BFP! Baby dust to all you ladies out there TTC. Question: how soon should I tell immediate family? Tmrw is Father's Day. Could be a great way to tell, but too soon?
