It is very unusual to have pink that many times in 2 months.
So it is unlikely you have pink eye.
Other causes that can mimic pink eye could be allergic conjunctivitis and blepharitis.
You should ask your doctor if he truly believes it is pink eye or if the other conditions can be possible.
I recommend using over the counter artificial tears 4-6 times a day. You should start cleaning your eyelashes as well with baby shampoo in warm water, scrub the bases of your eyelashes with the pads of your fingers twice a day.Please remember to press the accept button so I can receive credit for assisting you.
