I've been taking birth control for over 3 years now with very few mishaps. Last month/pack I had some issues where I actually lost a pill, and had 20 days of active hormones instead of 21. I got my period like normal and started this next pack a day earlier than usual because of that lost pill.
I only had sex with condoms while on this pack just to be safe, but then when I travelled home due to a time difference I ended up missing a pill one day. I wasn't even sure what day I missed - but when I realized it (probably 1-2 days later) I doubled up. I got my "period" this month but it's way lighter than usual - mostly brown, not that red.
Should I be concerned? I usually have a much heavier period. Recently I started working out pretty heavily and have lost only a few pounds - could this affect it? Should I be concerned about pregnancy at all?
