help please

been trying for years on and off. this month is the last month were trying! Im on Clomid, preseed, and premama! today I have cramps and a headache I just can't shake. one app said I ovulated 3 days ago and this app says today/ tomorrow. however I've been using clearblue sticks and I'm not sure if I have or am. then I just wipped and not sure if this is implant bleed or what. I shouldn't start my period till the 23rd. I've seen where the said ovulation bleeding is brow is and not red
