Hello
After taking emergency pills like Plan B your cycles will become irregular. It will take a few weeks for the cycles to regularise. Your usual date may not be the same again. These are just side effects of emergency pills. You are not protected from pregnancy during this time. Also frequent use of emergency pills are not recommended.

So is it okay for my second period, after the one plan b made happen, to be late?
About a week after that induced period stopped, we had protected sex, would that affect anything?

As i said, your period will be irregular for a month or so. It may be late and you wont have the same dates as before. As long as you have protected sex there wont be a problem with pregnancy. That doesnt affect your cycle.

How late does it tend to be? I'm due for it on the 4th, so is it possible i won't get it for weeks after?

well, you got withdrawal bleeding on 28th of last mth. You can be delayed by 4-6wks after that.

Even if withdrawal bleeding was march 28th? And it went into the day I was supposed to get it this month?

That why i said irregular at 4-6 weeks late. You should be getting it within a week or two.I had mentioned that the side effect of plan b is irregular cycles.This happens due to hormonal imbalance.
