My period came on June 6th, and ended around the 12th. I took a pregnancy test at my clinic on June 2nd I believe, and was negative. I have been on the Nexplanon insertion for over a year now. My periods are sometimes quite irregular. But never have been a week apart. I have light cramping, similar to my usual period cramps. It started off light pink, almost watery. I took allergy medication yesterday. This morning when I woke up, I had moderate bleeding, very similar to a normal period. I also have been having unprotected sex, but I highly doubt that I am pregnant. Should I just wait it out and see what happens? What do you think?
