Should i see a dr? Bleeding whilst on mini pill.

[4andnotout]

DD4 is 15 weeks now and bf, i have been on the mini pill for about 3 weeks and have been bleeding ever since i started it. It isn't a lot but enought to have to wear a liner. I also had a cervical erosion treated in 2005 which was diagnosed when i started to bleed after sex and the nurse couldn't perform smears on me as i bled too much. The erosion was treated and i went on to have dd3 & dd4.
Could it be the pill making me bleed or can erosions happen again?
Sorry if this is a bit rambly..

Its likely to be the pill, give it a bit more time, irregular bleeding can be normal when you first start it I usually advise give it 3 months to see if it settles down.
