You can definitely be pregnant for 2-3 months and not know.

I didn't find out I was pregnant until I was 6 months along...I know that sounds ridiculous, lol, but this is why:

~I had been on birth control pills since the day I turned 18, so it had been 2ish years by then of "control".
~I was still bleeding regularly every month at the same time, for the same amount of time...not heavier, or lighter, or longer or shorter.
~I wasn't any moodier than I ever had been.
~I had no morning sickness (other than a bout of supposed appendicitis that wasn't really appendicitis, but a near-miscarriage...that was maybe 3 months in, but the doctors didn't check for anything other than appendix problems. They just gave me pain killers and fever reducers and I was better in a week).
~I was very active at the time. We went bike riding every day with a friend, for hours at a time, and it was summer so it was 90ish degrees every day. We also went on walks and the occasional jog, so I barely gained any weight (I was already underweight at the time, so I was supposed to eat more to gain weight but we were exercising to stay in shape at the same time).

Point being, don't ever scoff that someone didn't know they weren't pregnant for any amount of time. It happens! Sometimes your body may fool you into thinking you're not pregnant, but it -can- happen.

    Around January (when I had pretty much just hit 6 months) we had stopped bike riding as much because it was winter and colder, and I was gaining more weight than planned, but I wasn't eating any more than usual. Plus, my tummy felt...firm? It felt kinda firm and slightly round-stick-out-ish, though not much. Also, I had missed my Period in December, and that made us take the precaution of getting a test done. The stick from Walgreens had said I wasn't pregnant, but we went to a doctor to make sure, and sure enough. They even did an ultrasound.

    Like I said above, lol, I cried and cried and I was in a state of panic for days. Trevor overcame his shock after a few days, and we talked about it for a couple weeks. He said it was completely up to me, that he decided he would like to keep the baby, but that it was my body and my decision...but for those few weeks, it felt like my life had been ruined until I calmed down and realized that we did want kids, we had talked about it before, we just didn't want them YET but here it was, so we might as well start now.

    Certainly did...We didn't even tell our parents about it for another half a month until we had decided whether to keep it, or do the A-word, or give it up for adoption, which I've already made a whole post about lol...once we did get excited, though (kudos to my mom for making me feel like it would be ok and being so unbelievably supportive about it) it did feel like a huge rush to all of a sudden need all sorts of baby stuff. I hit google, and I hit it hard!
