Hi, I'm 17 years old and I am sexually active but I haven't had sex in about 7 months due to stopping my birth control after having negative side effects while on it. Ever since stopping it, my period has been a little later every month and I usually have a VERY regular cycle of 32 days. On November 5th, my boyfriend and I showered together & we didn't have sex but his penis was very close to my vagina, but it never went in. Then on November 20th, I got my period and it was a normal period for 5 days. Since then, I haven't gotten a period and have no symptoms of getting one anytime soon. This past month, I have lost 9 pounds and have been more healthy, have been under a very large amount of stress, and have had strep on the skin (itchy red dots all over my body) and had to take strong antibiotics for a week, so I'm wondering if this is affecting anything? This last week I have noticed heavy discharge (it holds its shape) and extremely mild cramping in my stomach. I also took a hpt the other day and it was negative. I have no symptoms of being pregnant other that what I listed above so should I be worried that I am? Or is there something else wrong with my body? Please help, I'm super worried!
