Ladies who are having heartburn are you having a boy or girl?

I had it with my first two who are girls and did not get any at all with my third who's a boy, I have it all during the day with this pregnancy does that mean I'm definitely carrying a girl?

Thank you ladies for all your replies, we didn't find out gender at the 20 week scan , and now that it's the last few weeks I just can't wait to find out what I'm having 😂 . I was so sure the whole pregnancy that it's a boy but now I'm so confused, its going to be a realy long 8 weeks 😭
