Friends and fertility

Ok so some back story I've struggled with fertility for years and my midwife told me that after my first baby I'll be able to get pregnant easier. So we had our little girl who's four months old and I just got another BFP my friend has struggled with fertility the last four years after she had her daughter. We are cycle buddies so we tested together and mine was positive and hers wasn't. I started tearing up and I was trying to be positive for her like maybe it's just to early, if your not next month is right there, the whole nine. I balled because I wanted to be happy but I've only wanted her to be pregnant with me even prayed she would carry another child. well now she won't talk to me. I've had my fair share of false pregnancies, I've misscarried, doctors told me I'd never carry my own babies and to feel bad that God has once again given me two little lines and idk yet if it's a real baby or my mind playing me again.... I'm scared and my ultrasound is tomorrow to confirm pregnancy. I wanted my baby too but part of me wants to be able to tell her there is no baby so she'll talk to me again. I told her because I thought the worst thing you could do was to not tell them if you were pregnant. I struggled for years watching everyone else get pregnant and I was heartbroken yeah but I always was happy for them but it's been like a week and we normally talk everyday. Was I wrong? What should I have done differently? I just know it's not easy having a friend pregnant while you are struggling. I just need to take my fertility options while I can my ovaries are failing and I don't know when the doctor is going to say enough and take them from me. But I can't help but feel I've betrayed her because I got what she wants and I have begged God to give her a baby also. Sorry for the rant needed a safe space.
