TTC after 2 losses since December... what do you see??

Sarah • Married my best friend 11/12/13. We have 4 boys ages 8, 5, 5, and 3 (no they aren`t twins... we are a blended family).
We've been TTC for almost a year now. We got a BFP in December and in March, but unfortunately we lost both pregnancies (exactly 5 months apart). I've taken 2 tests and I'm not sure what I'm seeing. I don't want to tell my husband about the possibility until I find out if I'm seeing things from wanting a baby so badly, or really seeing them. Please tell me your honest thoughts.
