Genetic testing

Hi guys I need help deciding on what testing to get done. Either the sequential or the materni21 plus. I asked my nurse if I could just do both, not caring about the cost, because of my past it would just put my mind at ease and she told me I needed to choose. I’ve read the pamphlets they’ve given me and did some google research too but I still can’t decide! And no the results of the tests will not change my mind about how much I love my baby. I’ve had a difficult past and I just feel like testing would put my mind at ease or I could prepare for whatever the baby may have to make their life easier. Thank you in advance!
