BFP but lack of symptoms

We've been TTC for 3 months and last night I got 2 faint lines on 2 wondflo strips. I barely missed AF but the only thing I've been experiencing is sore bbs (with darker veins--thought I was going crazy but DH confirmed this last night). Today I tested with a FRER and wondflo again using FMU. Wondflo was still super light but the FRER was a definite positive. Couldn't quite believe it. I'd peed in a cup so I then took a Clearblue test--also a definite positive. I'm just worried that I'm not having any symptoms! Is it just too soon? I'm about 16 DPO. This is my first. Thanks in advance!
