hey everyone! i'm not really sure whats going on with me.. for the past few months i've been feeling really really sick. i have PCOS and my periods are EXTREMELY irregular. i haven't had a period in about 4 months; i had some spotting about a month ago but it wasn't my usual period because it only lasted 3 days as opposed to the 8 days my period usually is. i was on yaz birth control but stopped taking it about 3 weeks ago because i was afraid i might be pregnant. i've had extreme fatigue, nautea but no morning sickness, horrible back pain, i'm wicked emotional and have severe mood swings and cramping and bloating. ive had sex every week for the past 5 months with just using the birth control. i've taken about 5 hpt and they're all negative and i've been to the doctor and had a blood test and that also came back negative. i FEEL like i am pregnant but i'm afraid that it might be all in my head..someone help? i know this isn't just wishful thinking because i'm only 20 years old and def not ready for a baby yet..i just really want to know if theres a chance i could be pregnant. any help would be GREATLY appreciated!
