Whats wrong with me?!?!

You probably did just start your period. The dark brown/black spots were old blood. Where your just starting its most likely going to be really irregular periods. It will even out after a while. Don't worry about it, just get some pads and take some advil for the cramps. Welcome to womanhood! :)
If you are really concerned, then talk to your doctor, but I'm sure you will be just fine.

it probably means you are going to start your period. i got cramps in my lower stomach when i first started getting my periods but i stopped getting the pains after having my period a few times (though the cramps did start again about half a year later and i now get them on the first day of my period each month). the cramps are normal. you will be fine, but if the pains continue take some pain killers (such as ibuprofen or paracetamol)

This sounds as if you have started your period! Talk to your mum or dad whoever you confide in or maybe an older sister.

Hope i helped!

P.s i would advise starting with a sanitary towel, then after 4 or 5 months moving onto a tampon.

All the best :D

OMG u may have a hymen problem where it blocks too much of the opening. Tell ur doctor or see an OBGYN. they can break the hymen to allow it to come out. Otherwise u can get infections. Get help for it as soon as possible

You're fine, it's just your period.

its your period
