Northern Ireland- antenatel questions

I am looking for mums in Northern Ireland who can can give me some info. I recently moved here and am having trouble understanding antenatel care here. I am in a FB group with a lot of women from all around the UK (only in NI). They all seem to have had different kinds of risk screening tests and received notification if the chances of these. My question is: Are there any tests offered at all here by the NHS? Do I just give birth and hope for the best? I feel so scared that something will be wrong and I will be unprepared for it, but could have been for want if a simple blood test.

(Harmony is too expensive so please don't suggest. I am just looking for info about the NHS)
