I need some input please!

So, I had my nexplanon taken out on january 31st. I hadnt had a period on it at all except some spotting on jauary 17th. On February 1st I got a positive opk test! We didnt bd until 2 days later on February 3rd....now today I have this opk test, which looks close to a positive. So confused what is going on here. here is my opk from tonight at 4 minute mark. I also spotted for about a half hour on febuary 4th when i went to bathroom and wiped. then nothing after that.
