Is it really normal

Is it really honestly normal for a couple to take up to a year to conceive with no problems? Or do drs just say that? My husband and I have been trying since September. We are 24 and 25. No known issues. I went to my yearly obgyn appt and told her we were trying, she asked how long and when i told her she goes “oh really?! hmm. It can take a year” the way she said it made me question. She was acting almost surprised that we are still trying.

I’m worried there is something wrong with my husbands sperm 😞 I have a regular 27 day cycle. No pcos or endometriosis etc. I track with opks and bbt. I don’t understand why it hasn’t happened yet.
