Is this my BFP?

Diamond
So I'm now four days late. I tested last night didnt get anything. I tested this morning with FMU and was so dead tired i went back to bed and woke up with two lines !!! Is this it? Ive been nauseous. No signs of my period. Even tho it sat for awhile do you think it could be positive? Just little cheapies. This would child number two! My first is already 7 so im definitely ready.
