Doctor confusion.

Lily-Anne
I desperately feel like I need to see a doctor, but I don't have a solid reason why. 
I have been feeling so ill and off, I've been mid cycle bleeding on the pill, extreme breast pain, tired all of the time, a cold, headaches, and these all seem like good reasons to see a doctor, but I feel so silly going to a doctor when I could possibly just have the bug that's going around. 
I just don't even know. Should I see a doctor or just power through it?
