Need some encouragement

Today was my review with the doctor at the reproductive care clinic after first month of cycle monitoring. So my husband (age 45) has great swimmers and was referred to as “Ironman” and then he looked at me... I’ve been 40

For 7 months and I felt 75 after I left. Only 5 follicles and he basically said my eggs or egg is not so good. So he says 15k for IVF no guarantees. Husband says yes! I’m scared bc I had a miscarriage in September. I left feeling kinda bummed. I guess I’m no spring chicken but a seasoned hen. Lol. Ok Now my pity party is over. .. this can happen ...yes???!!!!!! Please share your stores with me.
