10 days late

My husband and I have been TTC for right at a year now. My period is 10 days late and I have taken three pregnancy tests which have all come back negative. I had a blood test 4 days ago which came back negative. I have lower back pain, nausea and sore breasts. I just left my doctors office and she wants me to take provera to induce my period and also add clomid after my period does start again since the pregnancy test they just did came back negative. She stated I should have had a positive by now if I were pregnant. 😔 We want so badly to have another baby but it’s not happening as easily this time. Has anyone had any success with provera and clomid?
