Confused When to Test

Jas

Hubby and I are just ttc I got my IUD taken out on 2/1 I haven’t had a real period since 2014, kinda forgot all the symptoms🙃 we have been actively trying without knowing when I ovulate even though I tried OPK.. now I have slight cramping and light pink spotting(one time when I went to the bathroom yesterday) and my boobs are more heavy then they are sore .. could this be AF or Implantation or Early Signs I’m lost🤦🏾‍♀️
