Soooo confused😩😩😩🤷🏼‍♀️

So i got my nexplanon out 2/22, BD 22nd and 23rd. Ovulated 2/23 & 2/24. Started spotting 2/25, very minimal.... Right before spotting i felt pregnant i could smell EVERYTHING, my boobs were so tender and sore. Now it’s 3/1 and I’m waking up nauseous. No spotting. Am I crazy? Or is this from being off nexplanon? I’m so confused at what’s going on.
