TTC after my angel babies

Cassandra
Hi everyone. I'm Cassie, i'm 27 from Wolverhampton, UK. 
 In 2013 i lost my daughter at 23 weeks due to infection. In 2014 i lost my son at 17 weeks and on 1st March this year i lost my daughter at 20 weeks. I have APS which is a blood disorder that causes miscarriage and premature labour. We are currently trying to conceive but i'm scared that its too soon. I am not trying to replace my angel babies but i have so much love to give. How long did everyone else wait?
