I'm 18 years old. I have accidents in the past that didn't result in pregnancies. (Thank God bc I was having a hard time in life.) Recently i have been sexually active without protection. (I know stupid.) Well I didn't have a period on time. My period comes on the 1st or the 2nd at the latest every month. It's almost two weeks late. Mind you before I has a urinary infection and was on antibotics and medication. But i stopped taking that about two weeks before my period was due. I first noticed that something was wrong when i was having period cramps but no bleeding. It went on about a little over a week. It in the past couple of days just stopped cramping. I was sick really early in the morning the first couple of days of my missed period. It got so bad that i had to get up and eat some salt. My stomach is always upset and i go to the bathroom maybe 7 ot 8 times a day. Not just urinating. I have skipped periods before but i never had the cramping without the bleeding. What do you think is wrong?
