Wednesday, medium positive FRER and hcg = 53. Friday... dark positive FRER (same as the control line).

Fast forward to sunday... we spent the weekend camping, and it's hot so I've been drinking a lot of water.

On the way home I stopped to go to the toilet and drank a bottle of water. 30 minutes later I got home and did an IC hpt and it was negative, maybe just a smidge of an evap / very faint positive. What gives? Surely the hcg can't be gone already if it is another miscarriage???
