I had unprotected sex two days ago with my boyfriend. I was off bc for a week because of headaches and i have been on camila for about 5 days now. I also have PCOS. I was bleeding last week after being taken off Kariva. but not sure if it was period or not because my actual period was 2 weeks ago. Today I feel bloated, tired, some nausea, and yesterday I was SUPER moody. Could I be pregnant? or is it something else?
