On the 22nd of June well I'm on birth contoll but we also didn't have a condom, so he pulled out and I was doing good on taking my pill at the same time everyday.. Could I be pregnant.. I'm Extremely SCARED.. and I'm still taking my birth contol, and I also got my period when I was suppose too... plus I had open heart surgery March 1st, 2007, so I also have chest pains from that.. and my boob that's above my heart always hurts is that just from the surgery or could it be a sign I'm pregnant.. HELP ME PLEASE :(

No birth control is 100% effective, so pregnancy is always a possibility. But, with you being on birth control, and taking it as you should, I doubt you are pregnant. Plus you used the withdrawl method, which is not a good method on its own, but works well with birth control.

Your sore breast is more than likely a result of your surgery.

The best thing you can do is wait it out. If you are late for a period, you know something is wrong. Then you can take an HPT and probably rule out pregnancy. Remember that stress can delay your period as well. The more you stress out about the issue, the higher risk that your period will be delayed anyway. Just relax and try not to think about it. :)
