At 7 weeks pregnant I had a misscarriage (it started 5 weeks ago and lasted for 6 days). How long does it take for hcg levels to return to normal? Two hpt show a fairly strong line after waiting 3 minutes. I had tried a hpt 2 weeks ago but as soon as I saw no line (i.e. I didn't wait the full 3 minutes), I assumed my hcg was back to normal. The only pregnancy symptom I had last time was sore breasts. I don't have any symptoms but some mild cramping on my left side. Is it possible I am pregnant again?
