Q: Fajr time I came out of washrum offered namaz then when I opened the book to recite surah yasin I felt some warm drops in my private parts. I thought that it was a waswasa and continued but after reciting I checked. There was very little moisture on my thighs and there were drops in my private parts which can be the result of water I used during istinja. I don't understand whether I was in wudhu or not?

Q: If a girl thinks of the opposite gender, some normal day to day things, nothing romance and she is not sure that something has came out of her private parts.
