In a previouspost from The Dark on endometreosis when is the best time for morning after injection she was in season 4 weeks thursday just gone so am i to late for this and if not how much is likely to cost.  With regards to spaying vet advised last year to have her spayed after her next season but I think I need to check when is the best time for this to be done

The morning after injection can be done within about a week of mating taking place. It costs around £150 (just to be safe, its probably less) and is quite effective.

Spaying, idealy should be around half way between seasons.
