I have three children, 13y and 7y twins all boys, both pregnancies were fine, I struggled at the end with the twins, however this pregnancy I'm struggling with and I'm only around 5 weeks pregnant. The constant nausea but not actually sick, the smell of certain foods, I've gone off lots of foods, the stomach cramps, so tired, and sometimes get a dizzy head, you name it I'm feeling it. Is this normal for third pregnancies or could it be I'm having a girl?
