i have severe gassy cramps, and nausea everytimes it flares up, my last period lasted about 10 days with normal for me is 6-7 days. I'm actively trying to concieve and be doing so for the last year, I've taken multiple pregnancy tests urine and blood and all come up negative. I eat right,(when i eat), and exercise when i can. Its really annoying and uncomfortable to do anything. Could you please give me an idea on what's going on?
