CD 27 light brown CM?

Per my dr. Instructions, I’ve been patiently waiting to take a hpt tomorrow on CD 28 after taking clomid CD 5-9. I’ve been having intermittent cramps the last 5 days or so, especially at night. Last night they felt like true AF cramps, but it weirded me out because I’m NEVER regular or ovulate (hence the clomid). This morning when I️ sneezed, some brown CM came out (sorry TMI) is this the beginning of the end for me? 😞 I️ was finally feeling more positive the cycle!
