I have been on the birth control for 4 years, and this month, I started the pill 1-2 days late by accident because the shipment. I then started the new pack of pills, and on the first week, my boyfriend and I had sex. We didn't use a condom, and he urinated before sex and pulled out (I know, not an effective method). I took a test 2 weeks later(earlier this week), and it was negative, I decided to stop the pill 2 days after the test to see if my AF flow would come and I guess it did. I had the same distinctive pain I only get on my period, and the I had some bright-ish red blood.MY mom looked at the blood and said I was definitely pregnant
Do you think my period started because I stopped the pill,or do u think I'm prgegnant

If this help, on the pill mainly due to irregular periods

You do not "stop" taking the pill, to see if pregnant, your body will start trying to have another cycle.

And no, she can not tell, that you are pregnant by looking at the blood, it does not work that way.

You are also testing way to early.

You have to just wait, and wait, till you are suppose to have your monthly cycle and see if you miss it. Then about one week after you miss it, try testing. (even then it may be false neg) and you may need to test again in a week.

You do not stop your pills. This only makes them less and less effective. So you need to use other birth control methods for at least a month for the pill to be fully effective again. (assuming you are not pregnant)

So:
Are you taking your pills again? Or have you just stopped taking them?
