None of this supposition is true, and going through the Internet and looking for trends doesn't tell you anything about your baby's gender.
Even if bleeding were more prevalent in male pregnancies (FWIW I have seen way more pregnancies with bleeding that were girls, but this may be because we have so many more girl pregnancies on this site) that does not mean that you are therefore carrying a boy.
There are biological reasons why bleeding happens. You can have those reasons occur with either a boy or a girl pregnancy. In at least one such case (such as placenta previa) that reason is slightly more likely to be in a boy pregnancy. But there are numerous causes of bleeding that have nothing to do with gender (and even the placenta previa link may not even be a real finding, these things are often debunked with future pregnancies). You just can't tell your baby's gender from something like this.
Most women who bleed do not have the same gender pregnancy. That is not a thing.
