What will happen if I took 3 morning after pills in a month?

Great job as always on this louis, so many are so far off could really do some damage.

You can throw the pregnancy apps out of the window for the foreseeable future.
This is a tricky question, for several reasons.
In short, yes, you could be pregnant.
There are no studies on the long term effects of such frequent use of Plan B.
It was never meant to be for regular use.
1 dose is a HUGE dose of artificial hormone for your body to deal with. It was meant as a one off, occasional, total emergency, drug. It is less reliable than regular hormonal birth control. It's simply worth a try in the event of no other option.
Many women become pregnant despite using it.

Women who use it more than once in the same cycle, tend to find that their menstrual cycle can be a mess for months. Their hormones are all over the place, as their body tries to find its balance.

You can have very intense versions of the symptoms you'd get with a period or pregnancy, for example. Bleeding can be heavy, spotting, none existent or prolonged. Mood swings can be fierce, or long periods (weeks) of temporary depression or aggression, can occur.
Abdominal cramping can be intense & prolonged, as well as things like bloating, breast tenderness, clear discharge etc etc.
Some find it takes months to get regular periods & normal hormone pattern, again.
As I say, it is unknown if it will cause you health issues, further into the future. There are no studies.
There are always some women who are not affected as much as others, but after so many uses, they would be rare.

I'm terms of whether or not you can be pregnant:
Plan B works by delaying your ovulation until the sperm leaves your body (that can take up to 1 week). If you were ovulating when you had sex, then Plan B can't delay what's already happening, & it would be the wrong choice of emergency contraception. In that situation you'd need one of the other methods of emergency contraception; either the other emergency pill called Ulipristal Acetate or to have an IUD fitted by a doctor. Either of those things can be effective if done within 120 hours (5 days) of the unprotected sex.

You could have become pregnant from the 1st unprotected sex you had, but for sake of this example, let's say you were not ovulating when you had the 1st episode of unprotected sex, but we're just about to. You took plan B & it successfully pushed back your ovulation by 1 week (for example).
The 2nd time during that cycle, you had sex 1 week later (just an example), & that was right on ovulation, because the 1st Plan B had delayed it until then. Now, this 2nd use of Plan B can't help, because you're right on ovulation. Now you get pregnant.
This means that you could have become pregnant from any of the episodes of unprotectex sex. It all depends on whether you ovulated (released an egg).
Only a pregnancy test will tell you. I'd recommend doing one even though you've had bleeding. You can still be pregnant.
