I need some advice... PLEASE!

Beth
Hi ladies, 
I've just joined, hope I'm not intruding. 
I have PCOS, and my oh and I have been ttc for 9 months. In September a consultant told me I don't ovulate and would need fertility treatment, however 2 days later on 4th, I got my BFP which was confirmed by GP. Anyway, within a week I had lost the baby, at around 8wks. 
Our best friends who have just started ttc last month have just (very sensitively I might add), told us she's pregnant, due June next year. How do I deal with this?? 
Oh and I are being referred for treatment with clomid, and while I am so happy for her (her oh has low sperm count, poor motility and morphology), and really want to be a part of her journey, I'm struggling with the emotional side effects and constant reminders that I never got to hear my baby's heartbeat etc. 
Please help 😔 xx
