I've been on the pill for 9 months now and it's worked fine. However,my last period which ended on the 30th seemed lighter than usual,but I did bleed for 5 days (it was on time and normal length). Is it possible that I could be pregnant? I take my pill on time every day,yet my boyfriend and I have never used any other form of contraception.
If the Pill is taken correctly you should not need any other form of protection, you sound o.k on that.
Around the time of ovulation the breast's can feel painful, lumpy or as you describe.
I believe you have nothing to fear.
As the previous writer said taking the pill can bring lighter periods.
