missed my occtober and november periods... and i got my december period.. i figured this may be from having way less physical activity because my sports season ended.. well i got my period the week of november 30 - december 6.. my periods are really irregular... we had sex on december 9... but like through december and first week of january i have been really dizzy like, i feel sick to my stomach alot and just really run down and just i am really worried that i may be pregnant but i waited.. i started bleeding really heavily with lots of stuff in it on the 6th of January... through the 10th. normally my periods are 7 days long and not that heavy.. well like the 15th i started getting really sick to my stomach all the time, really tired, have to pee more often again and light headed and dizzy, and i have mucus, and constipation and a burning in my vagina before and after i pee... i though maybe since i bled i had miscarriage.. but now i don't know... i never took a test to confirm anything.. and i don't know what to do now... so pretty much an advice would do me good... i wanna go to the doctor and get checked out but i cant because my parents cant find out and i live in a small town where everyone knows everyone so i cant just go and buy a test either... so any advice would be nice... and if i did have a miscarriage what do i need to have done..
