Please Help .

period was Aug 6 - Aug 9th .. about 2 days after i got off i started getting the eggwhite CM, didn’t think much of it because ive NEVER ovulated so early in my cycle before so was thinking it was impossible.. now im starting to think i did . usually ovulate between CD 20-26 .. seems its been getting more regular ( ovulate cd 14 ) as it’s getting closer and closer to that date each cycle that goes by .. my lines are getting darker AT all . actually seems to be getting lighter/steadily same color .. should i take a test to be safe ? has anyone else tested negative on a opk ( no peak ) and got a positive pregnancy test ? or should i just wait it out ..
