My youngest ds has a very rare genetic condition. A single gene disorder that has only several hundred cases in the world. I am struggling to come to terms with this and there is one thing that I am obsessing about to the point where it is ruling my head ALL the time to the point I cannot function properly. Myself and my dh have been tested for this gene mutation and neither of us have this so my sons mutation occurred de novo. The thing is I was taking antibiotics when he was conceived. Although they are deemed safe to take in pregnancy I have this belief that it was these that caused the problem. Please can any one help me with this. The guilt I feel is over whelming. I would do anything to turn the clock back and not have taken the medication.
