Could I be pregnant

🎀Ashley🎀

Okay long story short I had my daughter in June 2 weeks postpartum I got the depo shot and spotted until the middle of January and then I had a 7 day period in Feb okay now I haven't spotted or bleed since but for the last 3 days I've been nauseous around the same time every day (just like my previous pregnancy) I took a cheapie test and it a bfn have anyone experienced this before I'm so confused I'm hoping I'm not pregnant by daughter is only 9 months
