Is this an evap line?

andrea
So I just took this and it showed up right away...I took the pic at the 3 minute mark...but I feel as if it's an evaporation line...my cycle has been pretty regular since my ectopic and we were given the green light and I'm suppose to start clomid my next cycle...but I just had my period from February 25-February 29 which is actually short for me and it was very light...we weren't trying but we weren't preventing either...I should just now be close to ovulating and I keep getting only one line on those test and I have felt off all day so I decided to test to ease my mind since I am having a constant cramp in my right side...my left tube was removed from my previous ectopic...I just feel as if this is an evap line and I'm going to test again in the am but what does anyone else think? TIA...
