My SO and I have been trying to have a baby for some time now. I was pregnant once and had a miscarriage. Since then we have been trying and lately I've noticed my sense of smell has increased, I get nausea at night, and I'm tired all the time. But the thing is I had all those symptom but also tender breast before. Could I possibly be pregnant? I don't have tender breast this time so that's only thing that's keeping me from thinking that Im not pregnant. I took a test this morning and it was negative. But I start my period in 3 days. What do you guys think?
