I know this is a funny question but I am perfectly serious! I have been trying hard to get pregnant. Three days ago I tooted and it smelled so bad I wanted to run from it (poor husband!) and it has not stopped. Here I am still STINKIN like never before when I pass gas and I am eating the same stuff as before. (I do keep a food journal so I am truly aware of what I am eating and that it is the same stuff.)
That symptom usually showed up at about 8 weeks for me, and was on and off the whole pregnancy. Yes, it could be a sign. I usually get gassy a day or 2 before my period too. Take a pregnancy test and let us know!
