Ok, I am 2 months past my last period and my and my husband are trying to have kids. I am experiencing some back pain,nausea,i have to go to the bathroom a lot, and my lower abdomin is always tender to the touch,but I had a yeast infection like about 2 weeks ago and it said negative. So I am wondering if that would interfere with it but I am also wondering if I could be pregnant? Are these signs of being pregnant?
