I am 17 years old. I had protected sex a little over a week ago. However, it is possible that the condom could have broken. I have been bleeding almost like a light period except sometimes its only when I wipe. It's a pinkish browinsh blood, that every now and then is a bright red but mostly pink and brown. This is the third day, it comes with slight cramping here and there. Ive read that this could be implantation bleeding. What do you think?

WAY too soon to know anything.

You really have to wait until you are at least 2 weeks late for your period to test. And then you MUST do it right after you wake up the first time you pee... and only read the test within the time given in the instructions... not before or after.

Yes, it is very possible, Condoms have about a 3 to 18 percent failure rate, so while better than nothing, should be combined with another method for best safety.

Now it is just a waiting game, no way to know or test yet. So wait for your next cycle due date and see if you are late or not.
