Is it possible for plan b to affect your 3rd period.
Tracking with has helped calm my nerves about a lot of things since it also breaks down my cycle standard deviation, average cycle length, and current day of cycle so I can have a rough idea of what my body is doing.
Thought everything was okay I didn't have any side effects when I took the pills and figured it would be out of my system by then since they say it only effects for 4 or so days after.
