Thanks for discussing your concerns with us.
Actually this period of ovulation & fertilization is very sensitive. At this stage if an insult occurs to an embryo it usually gets aborted sometimes without coming into our knowledge i.e. without a clinical pregnancy
If the insult is below a critical threshold it may not effect the fertilized egg at all. That is an "all or none law" is applicable at this stage.
Simply speaking if pregnancy occurs this means the insult was below the critical level & has not effected your pregnancy.
If God forbid it has affected your egg at this early stage it will be lost without you being aware.
I hope I made my point clear.
Best of luck.
