Totally terrified

Olivia

Ok so back story I have a 4 year old daughter and since have lost two sons due to medical reasons at 12 & 13 weeks in utero (daughter was tested for pre-existing medical condition and was fine but the boys tested positive for the condition)! I’m now two days late for my period and am terrified to test! Although I do want to be pregnant I won’t know if I can proceed with the pregnancy until week 11 when I can have the test! If the baby has it they won’t survive past 5 weeks old! I’m thinking if my period doesn’t start tomorrow to test but I’m scared!! Anyone got any success stories to make me feel more positive?
