TMI PHOTOS Implantation Bleeding?

So sorry for the photo but I’m seeking advice. My husband and I have been trying to get pregnant for three months. I took a pregnancy yesterday (only 7 DPO) and got a BFN. But today (8 DPO) I started getting brown discharge. Once this morning there was A LOT of brown discharge. But since then, each time I wipe after using the restroom there is only a little bit like these photos. Could this be implantation bleeding?

I will say that I don’t have constant cramps like I normally do before my period. Its only in certain parts of lower abdomen, lower back has been bothering me here and there, and I’ve been having very slight heart burn/stomach ache that is not constant either. I am scheduled to start my period on the 11th, typically have a 30 day cycle. We have never had kiddos before so we are all new to this process! Thanks in advance! We are hopeful!
