Okay so im a little concerned about my lady business. A few days ago i started to bleed but it wasnt like period blood. It look like if i had been stabbed down there. After the bleeding stopped i got this intense pain in my lower abdomen, it left as if i got a thousand needles across my lower abdomen . It was a lot, it only bled like that for less then 2 hours. I told my mom about it and she said it was just old blood, that i was gonna start my period and id be fine. Well i just got my period aaannd so im a little concerned. Any clue what happen or what is wrong with me?
