Milk sensitivity during pregnancy?!

Ba
So I have never been lactose intolerant or had any issues with dairy but I have noticed that I get bad stomach aches after I drink milk or have ice cream and if I have dairy products before bed I wake up feeling sick. I thought it was just morning sickness that was lasting too long (I'm 24 weeks) but when I stayed with my parents for a weekend (They are both lactose intolerant so there was not a lot of dairy in our meals) my "morning sickness" disappeared. Then last night when I had ice cream before bed I got a bad stomach ache and then I woke up this morning and I was so sick to my stomach. Has anyone else experienced this or heard of an increased sensitivity to dairy while being pregnant?? Lol someone tell me I'm not crazy!
