I have never been pregnant but I think there is a possibilty that I might be. My last menstrual cylce began around 4/29-4/30. I had unprotected sex with my husband on 5/15. On 5/18 I noticed a brownish discharge on the tissue when I wiped after urination. That same evening I started cramping. The next 2-3 days I was cramping, nauseous, had an upset stomach. I have been taking the Monessa birth control pill for the past three months. I did miss the first three pills but I doubled up to make up for the missed pills and did not miss another pill going forward. Did I experience implantation bleeding and ovulation? If I am pregnant, it was not planned and I am afraid.
