Pregnant and having a period?

If the test said you were 2-3 weeks pregnant, then on February 21st you would already have been 4-5 weeks pregnant. That would mean you were already 6-7 weeks pregnant at the time of your last period. If you had a miscarriage then, you would have had clots or lost a gestational sac. So it's quite possible that the ultrasound is correct. My hCG levels also first went up before they started to drop after the early miscarriage. Just keep testing with the cheap dipsticks. Then you can see the line fade. That must be really tough for you both. I got pregnant right after the miscarriage, so it can happen quickly. And now everything is going well. By the way, I don't see a photo of your test attached?
