Are Mood Swings, Nausea And Vomiting Symptoms Of Pregnancy?

Ok, so I had my nexplanon removed on Tuesday (November 7) aweek and a half ago. And I missed my pill that night so I ended up taking Tuesday s and Wednesdays pills Wednesday (start of my birth control pill). No one told me I needed to start the pill a week before the implant was removed until I went and seen a new doctor about my gallbladder a week later. My moms gyno told her I would be fertile for the first 3 weeks after the implant was removed but I didn t know I would actually have a week s gap of being unprotected since I didn t start the pill a week ahead of removal. I had unprotected sex 2 days before the implant was removed and 5 days afterward. Could I possibly be pregnant? I have had migraines, I have wet spots in my underwear, I have been very moody and irritable, and I ve had terrible nausea and vomiting. I haven t had a period in several months due to having the implant. I don t know when I ovulate, or if I have. But I feel like it would be really early to take a test.
