Could I Be Pregnant?

I got my length on either December 13th, which be three days later than I be expecting it. I've been on the pill since September, but I took it something like 25-35 minutes late on the 14th. I have sex on the 20th. On the 25th, I started having this brown discharge and later I was bleeding a bit. For the first light of day, or so of that, I had pretty fruitless cramps. That discharge/bleeding lasted for just about one or two days. Since then, There be a couple of days that I felt a touch bit nauseous, but I don't know if that be just nerves or something. And I've also be really emotional and getting upset really slickly, but that could have purely been stress, and I'm also someone prone to getting resembling that once in a while. Does it nouns like I'm pregnant? It in reality just sounds resembling pill side effects. Missing a pill or taking it late can effect break through bleeding. Some women do report feeling sick. If you are still worried around it and you don't get your subsequent scheduled term then you know to use a prego try-out!! Also, different emotional states and mood swings are also some side effects of the pill. So, you could any be having side efffects or a outstandingly unlikely pregnancy.
it could just be that the pill is giving you trouble some women don't do resourcefully on it plus most women don't notice any signs of pregnancy until much subsequently...
