I have been on birth control for a while and woth.this months.pack I have missed 9 pills due to a lot of things going on in my life. I normally take my pills regularly. During this whole pack I have had un protected sex. On march 13-19 I had some light spotting. On march 27-now I have had very light spotting. My period is supposed to start on the 27/28. It is normally heavy from the first day to the last day and it lasts 3-6 days. This "period" is different and right this minute the spotting has stopped. My breasts have been tender on/off this whole pack and I have been very emotional lately and very tired. Could I possibly be pregnant? Or is all the spotting just from missing the pills?
