Implantation bleeding

April • Im a mother of three little boys. Two are mine and the youngest i have custody of til he`s 18. I love all three of my boys very much. I have a fantastic husband that i love very much.
Ok so earlier I got to the bathroom and I wipe and there's some light brown discharge anyone know what that means? My husband was licking and fingering me and it felt so different. It felt amazing lol. He said I was smoother and tighter down there. My boobs are a little sore and I get nauseous after I eat. I'm 10dpo so could this be signs of pregnancy? I'm getting a test tomorrow after my husband dentist appointment but I need opinions please and thank you.
