I have had more than a few Friday the 13th birthdays. No major catastrophies.

I had a miscarriage when I was very young and although I could get pregnant, I could not remain so.

My youngest child was born 2 months early on Friday the 13th and despite a rough couple of years is now a disgustingly healthy 27 years old.

Oh and I bought a house once with a credit score of 666

I always considered it a lucky day. In other realms - no problem - just another number.

I'm not superstitious.

There are various theories as to why 13 is considered unlucky, with the one most commonly given being that there were 13 at Christ's Last Supper. However, the superstition may be older than that: in some cultures, 13 is associated with the feminine as there are 13 menstrual cycles in a year, and the feminine (and menstruation) are often considered sinister or unlucky.
Triskaidekaphobia is still surprisingly common - many athletes, if assigned number 13 in a race or other event, insist on wearing their number upside-down, and there are apartment blocks that omit the 13th floor or apartment 13. Not all cultures consider the number unlucky, though - in Italy, it's considered lucky.

Personally, I think it's a load of rubbish.

It is based in the christain religion, there were 13 at the last supper, at least that is what I have been told.

Silly superstitions
