I am currently on CD50. I'm 24 years old. I've been feeling slightly abnormal within the last few weeks. Extreme fatigue, occasional nausea, heavy breasts (not really sore, just full), stretching type cramping in lower abdomen/uterus and lower back pain. I took a test last night and to me it appeared to be very negative. I took a picture of it last night and altered it today and I kind of see a very very very faint line. I just want a second opinion! I have slightly elevated testosterone levels but had a ultrasound done and all of my lady parts look healthy. I took this test with evening urine. If I don't receive AF by Friday, I will test again with morning urine. Thoughts in the meantime?! 🙂
