My fiancé & I are trying to have a baby, we've been trying for about 5 months now. I had my last period June 13th-16th, it's not supposed to be here for 2 more weeks. the past couple days I've been having sharp, cramping like pains in my uterus, I've also had a bit more discharge the past couple days, is this a good sign I could be pregnant? Or could there be something wrong? TIA
