Not eating enough?? Why am I not losing any weight?

Hi, how are you? That's good to hear. Me? Super frustrated.

So I've been working out like a fiend, eating super healthy, and haven't lost one pound.
I've been going to a spinning class 2 days a week for an hour (monday & wednesday mornings),
usually run jog on the treadmill for a half an hour- then do some weight lifting (60 dips for the triceps, 50 situps, bicep curls, lunges).
I added going to a bootccamp program once a week now (been going for 3 weeks now), which is intense- it's for an hour & we work all the muscles with resistance training, burpies, lunges, arms legs you name it, with very little rest period in between sets (about maybe a minute).

So I guess I've been working out at least 4 times a week (mondays I get a double workout with spinning for an hour in the morning, & 1 hour bootcamp at night).

With my meals it says I'm supposed to get around 1200 or so calories a day, which I've been doing- sometimes I get up to 1400. My food log says I've been getting too much protein (usually have 3 eggs in the morning, fish for dinner & a protein bar during the day). I've been trying to eat little snacks during the day every couple hours cause I've been told that speeds up your metabolism- I've only been doing that for the last week or so (I haven't logged anything before that on this website, just got on it a week a go!).

I'm wondering if I'm not getting enough calories in my diet, if I'm not eating enough? I know I'm working out hard, & I'm eating healthy, I don't know what the problem is! I usually sleep 8 hours a night as well, usually on mondays & wednesdays I take a couple hour nap after spinning, because I need it.

I've been going to the spinning class since mid January, & bumped up the exercise to adding in those treadmill days (I usually do that & the strength training at home late at night), & bootcamp just since the beginning of last month. I don't know, it doesn't seem unreasonable that I should be seeing some weight loss happening by now. One person did comment that I look skinnier, I seem to think I do a little when I look in the mirror- I know the scale is not a good way to access this, it's measurement . So I measured, I'm still at the same measurements I was when I measured myself this time last year! Frustrating, to say the least!

Before all of this I never used to exercise, my metabolism was always good & I only really ate one big meal a day & that was enough for me. I was super skinny, then I turned 30 & the gut came & hasn't made it's exit. I would like it to leave. I'm not a big eater, I don't get hungry all that often. I haven't drank soda since I was a teenager, I don't eat unhealthy in general (haven't eaten chips or fast food since, well I can't even remember!). So there's no probelem with being hungry. Ususally I'm not. But my gut would tell you otherwise. I't's always just there, hanging out, checking out the scene ;P

I don't want to give up cause I really want to be fit & toned, but I just have no clue as to what I'm doing wrong. My bootcamp instructor isn't a nutrionist so he can't really tell me what the probelm might be.

If anyone out there can give me any help, I would greatly appreciate it! I got so frustrated yesterday that I had about 5 beers to take the edge off, but since I didn't really eat too much yesterday I figured at least I'd be getting my calorie intake right!

Please, if anyone could tell me what they might think I'm not doing right, it would be very much appreciated.
I believe my profile is set to "open to everyone " so please take a look if you can.

Oh and excuse the screenname I couldn't think of anything else at the time, kinda lame
Thanks!
