<s>[INST] Hi , I started using gildess fe 1/20 contraceptive pills last month , starting day 1 of my period . The 3 weeks of active pills got over last week and I started the brown pills . However after starting the brown pills within 2 days I had very minimal bleeding that lasted not even for a day - so I got confused and started a fresh active pill on that 1st day. However since I did not have bleeding after that , so soon o stopped taking any more of the white pills and continued taking my brown pills from the first pack as I should have. After I finished that , I started the 2nd white pill active pack starting this Sunday ,may 5th --- however now nt having any periods and I kind if missed my cycle I guess ? I am very confused and scared as I seem to have messed up my cycle . I am generally very regular on my periods and do not have irregular cycles . Please advise what should I do now ? Is thre any chances that I may be pregnant ? [/INST] Hi there ~I understand your concerns.  To allay your fears about pregnancy it might be best to take a urine pregnancy test (UPT).  I also believe that you should not be switching over to the new pack if you have a period and go back to the new pack again if you have breakthrough bleeding like you had the first time around.  I believe that you should have continued to take the brown pills.  It is not unusual to have either breakthrough bleeding while being on the pills nor is it unusual to have variations in the cyclical periods when you are on the pills.  Also skipping periods is normal in these situations.  I hope this helps answer your questions. Take care and have a lovely day! </s>
