... stomach most of the time, my breast and nipples are sore since then and my breast gets swollen sometimes. I even had one day where my nipples were leaking a little cloudy liquid. Just last night I had a horrible headache and I took a pain pill with caffeine, an hour later after I ate dinner my stomach felt really weird. I had a bit of diarrhea and then I felt really nauseated. I'm not sure if I could be pregnant, my husband and I are using protection by condoms since I got it removed but I did have unprotected sex before I had it removed. The first two years and 7 months while on the Implanon on I didn't have my period at all until the last 5 months I started having regular periods. Is there a chance I could be pregnant since before I had my Implanon removed, or could it just be the removal side effects, and should I wait and see until my period is supposed to happen to take a pregnancy test or should I go ahead and take one?
