Ugh, I don't have them often but when I do they double me over. Good thing is they don't last long either. Maybe 2-3 times a day less the 5 mins at a time. I do have a terrible cold, coughing my guts out. And my period cramps were far from normal, but I was hoping this wouldn't carry over to pregnancy! Anyone else in the same boat? I also just got my hcg tested on Friday and it came back great so that shouldn't be the issue.
