is thid af? cd30

so i called the doctor this morning to ask if clomid can make ur period later.
she said no. that i could hpt now or wait.
this is cd 30 and no af so she said to test on oct. 27th(1 week late)
freaked out all day cuz still no af. anxiety anxiety anxiety am i or arent i am i or arent i?
then at work at 730 pm had odd black(sorry if tmi) clumpy discharge. this is not normal for me and pretty gross and confusing as hell. wtf is that? my period? God i hope its not gonna look like that now. just comne one if your gonna come on, ya know??? no back to spotting. no cramps at all. feel a cold coming on. sore throat.
no af but very light brown clearish spotting (which dr say is normal, even if ur preg)
is this normal clomid procedure???
sooooooo confused
