firstly i know what you are going through and its just horrible, i have been in your situation 3 times, 2 times with natural pregnancies and 1 IVF, we didn't have any frosties so we decided to do another cycle with pgd to test embryos as we were told the chances were they were all because of chromosome problems.

Of 4 we had tested they were abnormal which makes sense that the losses were from that

There is no need to rush your decision now, give yourself some time to deal with this
