In need of a little hope

My husband and I have been ttc for about 2 years now after going through a molar pregnancy. These last few weeks we thought it might have finally happened because my period was 2 weeks late. I got my period 4 days ago and the same day my bestfriend finds out she’s 5 weeks pregnant. I’ve been so depressed and this just added on more. I am completely happy for her and wish her all the best but it does make me a little sad because all I can think about is when will it be my turn. :( just needed a space to vent
