Just starting preparation month for IVF and have DET booked this pm. Consultant said not to have unprotected sx until a few days after DET as it can cause miscarriage. DH and I did have sx over the weekend though on the basis that I usually ovulate around day 11 or day 12. I think the earliest ever is day 10. Are we ok to go ahead with DET? Would be sod's law if we conceive naturally this month then miscarry due to DET.
