6-7weeks - nausea?

Hey ladies- I'm going into what I believe is my 7th week. All weekend I have been unable to shake the feeling in my stomach. It feels crampy and gassy no matter how well I eat or how much. This is making me feel very nauseous but I haven't thrown up. I've tried peppermint tea and tums but it isn't helping. Does anyone have any suggestions? I feel like I've been so unproductive this weekend and need to be more productive at work this week but I'm already off to a rough start. Woke up to go back to the couch and turn on my heating pad to sleep for another 45mins .... thanks in advance!
