I hope you are right...and the first week...i didn't but i thought that it would be okay since i only jst missed a month or two (on the ring) and When i first started the ring i didnt know the one week rule and when the condom broke i panicked but i was fine...but im panicking now (with the one week reminder) which could also push my period back and induce symptoms of pregnancy w/o being pregnant (psychology ***** haha).
It could just be your body readjusting to the hormones of the birth control again, which is very common and what I think is going on. Though did you use a secondary form of birth control in the beginning? Typically, when you start any new hormonal birth control regiment, you need to use back up(condoms) for at least a week, but usually about a month long before the hormonal birth control becomes effective. I can't tell you if you are pregnant or not, as you will just have to wait and take a home pregnancy test to find out. You can take a home pregnancy test 2 weeks after having sex and get an accurate result, or just wait until after a missed/late period, if that is the case. Hope it all goes well.
