LMP 7/8 - Got a vvvvfl 8/12 (af was due 8/8) A week later 8/19 I went in bc due to LMP I’d be 6w. But I knew I couldn’t be 6w bc I got a faint positive 4 days after AF was due which would mean I’m prob 4w. Anyways I went it on 8/19 thinking I’m 6w took a urine test and it was still faint since the first test I took on 8/12 it hasn’t gotten darker. Definitely show it’s positive but not darker than the control line. Doctor did a transvaginal and saw what is the uterus line but no sac. He said I could either be too early or etopic pregnancy/miscarriage. I’m worried because I took a test last night around 9pm and the line was super faint barely any color but still a pink thin line. My symptoms have disappeared (sore boobs, fatigue) & I had a miscarriage in March I was 18w. It was my only miscarriage my others were healthy babies. I have no blood or cramping but I’m still kinda bumped, sad especially after seeing the test won’t get any darker. What do you guys think? Based of the dates am I too early? Did I ovulate late? I see the doctor again this Wednesday hoping to see a sac.
