I'm 16 years old. Recently i had a very odd period. I had unprotected sex on the 9th of december and my " period" came on the 22nd or what i thought it was at least. When my period started it was a dark brownish color. It looked like dry blood and there was only a few spots not very much. It stopped for a while. I was confused at this point. a couple of hours later it started up again except it was fresh blood and it was bright red it had a little bit of brown in it. But i thought i was having my period so i let it go until now. I'm tired all the time. Hungry all the time. I have to pee a lot. I have headaches and i'm lightheaded and i just feel off..more than that i can't seem to get to sleep at night..and before the insomnia came about i was having really vivid and strange dreams..I'm moody. I can go from happy to sad in 2 minutes. I cry all the time it seems like..Could it be possible that i'm pregnant? That i had implantation bleeding then just was bleeding but none of it was my period..I would buy a home pregnancy test but i don't have money. Can't seem to find a job and i don't want to bring it up to my parents yet. There is just so much going on..I don't want to stress them out..Im so worried. I just feel so ..off lately.
