i have been getting naseous at night around the same time, gagging but not actually vomiting. my breasts are sore and I am tire. My period was due today but nothing, not even spotting. I am pissy and I feel achie, I also have these weird pains that feel like pulling pains in the area bellow my ovaries. I have been having these for the past 3 days after having intercourse with my boyfriend. could I have pulled something? or am I pregnant?
