So devastated

I honestly don't know what to say. I had 3 BFP as clear as you like, sickness headaches back pain achy breasts & all of a sudden the midwives say it won't be a viable pregnancy due to low progesterone and now I'm bleeding. 8 weeks of joy and happiness to complete devastation and confusion. I don't know if we will have the strength to try again or the trust in any tests. Nothing even confirms anything with pregnancy until you get those numbers back, the rest for us has been a complete lie.
