Typically my cycle is 34 days with ovulation on day 18. I got off birth control 6 months ago. This month I ovulated on day 23 but still no period. I am 43 days into cycle. My husband and I are TTC with sex every other day throughout entire cycle. Currently experiencing swollen breasts, headaches, nausea, and brown spotting with negative pregnancy test on day 39. Could I be pregnant?
