I am 17 and I have been on Lutera birth control for about 9 months. At the end of January (it's now the end of February) I began my period on the white pills and I continued taking my pills as I was supposed to but afterwards I started to have brown discharge and light bleeding since then. At the end of January I took a pill late I usually take it at 7 am but took it around 11 pm. I have been having brown discharge since then and I have had sex twice too. Once protected and once unprotected but my partner didn't cum in me. I was wondering why I am still having brown discharge since it's been like 3 weeks since I took my pill late??? Is that the reason or could there be another reason??
