I had a mmc in 2010. I can't explain why but I knew from the second I got my bfp I was going to miscarry. I did at 7 weeks.
I then got pregnant with my gorgeous Ds who is now 2. I had a bleed lasting 3 days the day I got my bfp. I was so worried it would end in tears but at 8 weeks I saw my beautiful baby on a scan monitor and cried my eyes out.
I ended up reacting badly to pregnancy hormones and went into renal failure. Some doctors tried to make me have an abortion for medical reasons I refused.
I had a traumatic birth and ended up on ICU but my beautiful boy made it all worthwhile.
I got pregnant again before he was 1 but lost the baby quite late in the second trimester (On Christmas Day ) I later found out that the hospital had severely damaged my cervix through negligent treatment when I had ds. They didn't tell me at the time in case I sought damages.
I got pregnant again 2 months later. I had to have my cervix stitched to prevent late miscarriage again. I went into premature labour a couple of times and finally had my gorgeous dd at 39 weeks by c section.
Due to how much damage I received at the first hospital when I had ds at my uterus ruptured during 2nd labour I almost bled to death (I needed resuscitation )and I can't have any more dc but my 2 dc are my little miracles and I couldn't be happier.
When you're in the thick of the situation its awful you feel like It will never happen for you. It physically hurts to hear of others having babies, not because you're not happy for them because you are. It hurts because you never know if it will happen for you.
But Miscarriage is so common, so common in fact research suggests the miscarriage figures are much higher than currently recorded 1in4 because people miscarry before they realise they are pregnant.
Anyone who is going through mc and ttc atm I'm so sorry if It has happened to you. I wish you luck with the future. One fact I clung to was that most statistics show that most women (about 70%) go on to have a baby within 3-4 months of their original due date. That got me through the early days with my Ds and Dd.
Another story (not mine) I had one friend who ttc for 11 years then got pregnant with twins, decided to try again had 2 miscarriages thought it wouldn't happen again and then got pregnant again. She had her dc and got pregnant (surprise pregnancy) when her 3rd dc was about 5weeks old. She tried for 11 years then had 4 babies in 3 years 
Miracle babies do happen otherwise there would be no posts on this thread
