I know every pregnancy is different but this is making me nervous!

Mimi • Momma bear 🐻 expecting her second cub💙.
I'm 9 weeks with baby #2 and I've had horrible nausea and vomiting here and there. With baby #1 I had no symptoms at all just occasional back pain and cramping. I'm having some tingling sharp pains in my vaginal area. I'm so confused it's not like painful but just uncomfortable 😣, I am hoping for a daughter this time around. This tingling feeling comes and goes whenever, i am nauseous almost all day and night long. This pregnancy is way way different then my first. Yet everything scares me or makes me nervous because I've never experienced it before. Is this tingling sharp feeling normal? Also are a lot of the old wives tales true? My son told me he was having a sister when I first found out and, my husbands step mom had a dream my son was telling her I was having a girl. But now he's telling me he's having a brother and sister so I'm so confused because I know there's no twins in my belly! How many wives tales are actually true?
