Hi all, I am 15w pregnant after IVF and have just been told I have low Papp-A (0.35). I just got sent a letter in the post and it has no mention of aspirin or anything. Should I be worried that I have not been asked to take it? I have my 16week appointment next week with the midwife, should I ask if I can take it? I feel really anxious to not do anything. Would appreciate positive stories about pregnancies with low Papp-A also.
