Confused

So I went Wednesday to have them verify where my Nexplanon is since it moves all the way from my armpit to my elbow and I’ve been having abnormal heavy periods. The ultrasound tech said she couldn’t find it but could see the shadowing of it. I took a pregnancy test a few weeks ago and it was negative. Anyways I have been bleeding very heavy and having pain but see my ob in a few weeks. They moved up my appointment to next week but otherwise said to go to the ER. I wondered if I am having a tubal pregnancy or miscarriage or a cyst has popped. Do these look positive? First picture is last night after work and the second was about 330am this morning.
