I'm on norethindrone .35 birth control tablets. 3 days ago I started spotting on vacation 2 weeks after my period. I started taking two tablets for 3 days hoping it would stop the spotting. It did lighten it but my breasts have been extremely sore. Will everything be OK after I took my pills like that? What could cause my breasts to hurt like this? I should also add I'm 32 years old, no children yet & am sexually active. Could I even conceive on this medication & if I did, will the baby survive being that I took my pills like I did? Thank you
