I have irregular cycles and can't remember the last time I had one. I know it was in May sometime. I started spotting a brownish looking... something last Sunday. I recently noticed the urge to urinate more often, gas/airy stool, occasional single cramp on my right side, nausea and tons of fatigue. I stopped spotting 2/3 says ago and wanted to know if I could possibly be pregnant? And if so, how long would I wait for it to show up on a hpt? Btw- I'm 31, no kids and trying for baby #1! Scared and nervous.
