Tummy Issues?!

Heather • Mom to a wonderful 1 year old girl. TTC #2 since April 2014.
Anyone else have tummy issues? I think I had too much dairy today (pasta with cheese & pudding) and now I'm in so much gas/BM pain! I started keeping track as I tend to have one bad episode every month so I thought it was hormones, but as it continues I'm thinking it's a lactose intolerance :(
