Idk what's happening..

Kenzie • 21 and happily married! We’ve been trying to have a baby for 2 almost 3 years now with no luck.. I turned here for answers and have gotten a lot of positive help and feedback! 💕
I haven't had my period in 3 months. I went to the doctor and got a blood test done and it was negative they told me to wait a month to see if my period would come and it hasn't. I'm scared it could be something serious but also secretly hoping that I'm pregnant and the tests haven't detected it yet but that only happens in the movies.
