My periods are irregular but I track when I ovulate based on CM and BBT. When I ovulated on March 7,8,9, and 10th, I took BabyDance fertility lube every night before sex. Last night I spotted and have been very moody and weird-feeling. Is it AF or should I wait and take a test to make sure? help please. Only spotted yesterday for about a hour and then it went away. Bloated and feeling gassy and cranky. Have very painful cramps.
