Scared 😖

I'm 9dpo and today I've had some pinky/brown discharge. Not a lot, but enough to notice. This is my first month on clomid and I'm worried it could be AF coming early! After I ovulated I had very strong symptoms, cramps, feeling sick, sensitive nipples. Yesterday I had bad cramps and thought It was definitely AF coming early, this morning I woke up and felt normal again so thought it must all be in my head but now this has happened and the cramps have come back but a lot milder. The only other symptom I have it my breasts have got very big! It's not abnormal for me to spot a few days before my period but I'm not due until Sunday (7th) and I never get cramps with the spotting. It's more discharge then blood anyway. What do you think? My SO and mum think I'm going crazy. I guess I've just got to wait it out... Has anyone else experience anything similar?
