Cycle is messed up!

7 weeks today I have had my nexaplanon removed, still no period, not had a period since I found out I was pregnant back in 2016. Faint positives on cheap tests, two different brands, negative Frer. What is going on?! I'm going to retest at the end of the week. I'm just having rant. Is it possible to have so many false positives?
