Had a miscarriage at 9w1d on 3/1. Belly seemed to be growing/ bloated and nausea stuck around. Took a hpt on 3/15 on (25u dipstick) early test and it was blotchy but positive. Took another hpt on 3/21 and it was also blotchy positive. Took another on 3/23 and it was BFP not blotchy. Could I be pregnant again so soon? I had unprotected sex 6 days after miscarriage as my bleeding had stopped completely, but used pull out method.
