Brown discharge

Hey guys! These past few days i have been experiencing mild to moderate headaches. And i am guessing maybe it is just the weather which is getting hotter since summer is almost approaching. Or maybe my period is coming up. I am not sure because i have an irregular period. Meanwhile, i have been having white vaginal discharge for days, its not sticky tho. The texture is some kind of clumpy. Then earlier today, after using the bathroom, there is this brown sticky vaginal discharge that came off from me. Its my first time experiencing it and i am a bit worried. Cant go to a clinic for a check up because of this pandemic situation. Does anyone here experienced the same?
