Background: I had a chemical pregnancy last cycle. I have a very healthy 3 year old. I've been TTC #2 since OCT '14. 
I started testing at 9 DPO got a squinter with FMU. Each day for 3 days I have received a squinter with FMU. I'm worried it could be another CP. I have so many symptoms. My lower stomach is already rounding out like I'm half way through a pregnancy and very hard. Lots of other symptoms as well. Did any of you get squinters for several days before you got a faint line?
