Does having 3 girls raise your chance of having a boy next?

I have a friend in the HT group who has 4 girls. She did HT for a boy. It split & she has just delivered identical twin boys. Bless.

It didn't work for me and I know heaps of women with 4+ girls.

I am the 4th DD out of six girls but my DH is 4th out of 3girls before him and 3 more girls after him.
