i am 22 F. i had my periods last month on 16-20.After that, i had sex on 29, 3 and 10(he used protection). its 19th and i haven't got my periods yet. also i am always irregular on my periods. On 16 & 17, i experienced light spotting and pain in my stomach which was mild. i am going through stress for past 4-5 days(because of exams and afraid if i am pregnant). i got scared after watching that spotting and took a home pregnancy test on 18th which came negative. when i came home, the same day i saw dark reddish- brown discharge on middle of my panty(about 15 drops if it was spotting).i also experienced same pain when i get my usual periods i.e. lower body, legs and abdominal pain. i thought my periods had come so i used a sanitary napkin. this morning, there was nothing and when i used toilet i saw blood again. it was dark-reddish brown drops and was not as thick as my usual periods(usually dark reddish). i assumed my periods will start today and this is the beginning of it. so i used napkin whole day and again nothing was there. i used toilet and again i saw same blood. i haven't got my periods yet. and did not experienced ovulation during this time. what can be the reason behind this discharge? please help me out! i am freaking out!! :(
