This is my first month on microgestin but I've been on birth control since July. I just took my last pill before my first placebo pill at 7am this morning. Tomorrow is my 1st placebo pill. It's been 3 hours since I took my final pill and I've noticed a brown discharge and a little chunk similar to the lining chunks that come out during your period. Is this normal? Other than mood swings I've had no problems on this pill. Thank you for answering all my questions. I new to BC and I do not really have anyone to talk to about it without consequences.
