I am a 25 year old woman with pcos diagnosed 2 years before. I was put to krimson 35, 2 years before and since then I ve not missed a pill and take it at the same time. I start my pill pack on sunday night (5th day of my period) and my 21 day pill pack ends on saturday night. After that I generally get my period on wednesday night or thursday morning. My last period was on 12th june (wednesday), I started my new pack on 16th june (sunday) and on 19th june (wednesday) my husband and I had protected intercourse with no tearing of condom. I also take my pills same time everyday. On 1st july (yesterday) night I felt brown discharge from my vagina and in 2nd july (today) morning I also saw few drops of blood (pink, red). I am continuing my medicine as usual and my pill pack will end on saturday (6th july) and the due date of period is scheduled on wednesday (10th july). I have no plan to conceive right now. Should I be worried about pregnancy after taking all the safety measures (condom as well as pills without missing one)? Was it some kind of implantation bleeding? Also I felt uneasy at the time of that discharge. I did not vomited and the condition did not prevail much longer. But there was some sort of nausea. I am not feeling anything else as of now except for that is there any chance of conceiving? I also have excess caffeine intake that day. Should I be worried about pregnancy at all?
