Im 19, female. Been having chest pains frequently now. Today to top that I had a bad headache and is continuing to have a sharp stomach pain which started about 1 hr back. I do not usually get this type of stomach pain, even with cramps it is less painful or different. About two weeks back me and my partner had sex about a few times. As a safety measure I even took a contraceptive pill (i-pill). I had my periods the same week and it was not much smooth. Had severe cramps but still manageable. Had the bleeding from 3rd to 9th this month. Last two days of that, my bleeding was less. Need advice on what to do and what this could be due to. Thanks for reading.
