Maybe someone can help me! 😔 I have been tracking my ovulation for a min now, I know when I ovulated, the 16th and I had sex the 14th that same week i was feeling cramping like my period was trying to come on, but didn't. There was no spotting just nauseous, tiredness, hurting breast and cramping!! I have been tracking my BBT also it's been in the 98.8 range, my period is due the 29 but don't feel like it's coming on I tested yesterday and got a Negative! Ladies what's should I do
