I heard that the morning after pill does not work as well in overweight people. Is there any truth to this?Updated 2 hours ago

There is no weight limit. It's still recommended to take a Morning After Pill if you need it, regardless of weight, though some studies suggest it may be somewhat less effective in preventing pregnancy for those with higher BMIs or weight. The most important factor is timing: the sooner you take it after unprotected sex, the more effective it will be. Timing of dose is the most critical factor, not weight.
