SO FED UP!! CANT STOP CRYING!

I am so fed up! My fiancé and I have been trying to conceive for 14 months, we thought this was our month but af decided to show her ugly face!! I have an obgyn appt tomorrow to see what the hell is wrong with me! I have seen friends and family become pregnant and have their babies. I have seen people miscarry and now pregnant with their rainbow baby and we can't even get pregnant once! We have tried everything! ovulation tests, pressed, apps, I take prenatals, we even bought one of those sperm fertility checkers and it came back super positive super quick so I know it's not my fiancé!  Everything and still nothing! I feel so hopeless and I feel worthless because I can't give my fiancé the baby that we want so bad! We already have a room with a crib in it, waiting patiently but the door stays closed because I can't even look in the room anymore because it feels like I'm never going to be able to decorate for a boy or girl or see a baby in the crib...I'm really hoping this doctor can answer all my questions and prayers tomorrow, hope I don't get bad news! Baby dust to everyone in the same situation and trying to conceive! I'll pray for you and wish you the very best!
