Dairy intolerant except with pregnancy?

Is anyone else intolerant to dairy normally, but tolerating with pregnancy? I usually suffer with gas, bloating, belching, diarrhea and much pain. Lately I've been noticing dairy isn't effecting me the same, so I'm pushing my tolerance daily, to find the limit and convince myself I'm not imagining this. I have been intolerant to diary for 2 years now, shortly after adjusting to a gluten free diet due to Celiac's Disease (I've heard the two can go hand in hand). Wondering if anyone else has experienced similar.
