9 Days Late with Negative Test

Sabrina

My husband and I have been TTC. I used the app and ovulation test to determine high and peak ovulation. We tried all 5 days I ovulated. I am currently 9 days late. I have taken 4 pregnancy test an all are negative. Could I be pregnant? I went yesterday to my obgyn, they drew blood and are going to let me know Monday those results. He said he could give me a pill to force my period to start. I'm afraid to take it, what if I am pregnant? Anyone else have this happen?
