Wake/funeral while pregnant?

I have heard old wives tales that it is bad luck to attend a wake or funeral while pregnant. Just looking for some reassurance from those of you who have attended and everything turned out fine. My friend's sister passed, so I really feel like I should go, but have had three prior losses so I don't want to jinx anything.

UPDATE: Thank you all for sharing your experiences and reassuring me. I decided to go and I am glad I did as my friend was grateful to see me.

Last ultrasound was at 8 weeks and everything looked great. Baby had a heart rate of 160. We have another ultrasound scheduled for next Monday, hoping that everything will still look great. I guess it's just one of those things where you don't want to believe in it, but then there's always the "what if it's true."
