A sad story happy ending

Shona
So back in 2011 i got pregnant on october 3rd. Went to the dr took the test to confirm pregnancy found out i was 4 weeks. My husband and i were so excited to be having a baby that i was told i couldnt have. Well come to findout it was twins. One night i went to take a bath before bed so i could relax a little bit and when i went to get out i couldnt move i had to have my husband lift me out of the bath tub and help me stand up. All was ok except i didnt feel very good had a few cramps thought well its normal im in my early stage. Well was i wrong!! I went to go lay down after my bath then got up to go pee and thats when i seen blood not a little blood it was a lot i was scared started crying telling my husband to take me to the hospital now i am bleeding and now i cant walk (after using the potty) so he called his mom to take us and sure enough it was a miscarriage. That hospital did not have anyone on duty for the ultrasound to be done so when we left there we went to another hospital to get the scan done and sure enough i lost one of the babies. I am still so heart broken over it. Always wondering what the little bean would have looked like and if it would have been a boy or girl. I still to this day get depressed over the what ifs and what could have beens. My baby would have been 4 on 7-4 rite along with my son, the baby that survived. He is a happy healthy gonna be 4 year old boy that started head start this year. 4 months after i had my son i had gotten pregnant with my 2nd rainbow baby my daughter she will be 3 this August. 
I have pcos and was told that i will never be able to have kids because of it but the dr had me take clomid to "try" to get pregnant (the first time) and it worked. Idk if u guys would think of my son as my rainbow twin or my daughter as the rainbow baby but i call them both my rainbows because they both came after my dreaded partial miscarriage. I have never heard of this happening to anyone else and god i pray that it never does because it is heartbreaking. 
JUST REMEMBER EVERYONE THERE IS ALWAYS HOPE. We are currently trying for baby # 3 (or 4 actually) and i always fear that the samething will happen again or maybe i just wont be able to get pregnant again. My daughter was concieved on high breastfeeding hormones and i am thankful for ALL of my beautiful babies.
