Only fmu shows a vvfl

So Sunday night I took a first response text, it was negative. Monday morning with fmu I took another first response test, and I thought I saw a line tweaked it, and it was there with color. Took another one today second urine of the day, and it was negative. Af isn't due for 3 more days. But my breast haven't stopped hurting since af last month, I'm super sleepy, and for about 4 days I have been really queasy feeling, and having to pee more often. Which is why I have tested. Is it just to early to test, or should I only use fmu. Any advice is much appreciated. Thanks ladies
