Anyone have any input or experience with this? Plz help.

Long story...Ok so I wasnt really tracking O, temps or anything this cycle. The one thing i know for sure is the date of possible conception 5/15. About 9 days later on 5/24 I had what I thought could be implantation bleeding (pinkish but mostly brown only when wiping, lasted 1-2 days, light cramping) the cramping has been super mild and lasted on & off ever since...Now AF was due yesterday 6/5, only slight brown spotting, and same today also light cramps as well. Usually my periods are almost like clockwork give or take a day. I will cramp outrageously for about an hour and then the flow starts & no more cramps the entire time which is about 5 days. Also normal flow starts pretty heavy and tapers off last 2 days...Anyway basically whats going on now isn't my norm....Also ive had very mild, symptoms nausea, loss of appetite, slightly sore breasts & more recently burning nipples, headaches, somewhat tired etc. I tested 6/1 with FRER, which was 4 days before AF & got what I think wasan extremely faint positive. But retested yesterday with ClearBlue Digital (negative) and a Dollar Tree test (i think negative or possible dye run). So idk what to think. 😞 Idk of this brown spotting is a period or just some type bleeding ive read so much about in very early pregnancy. So frustrating, trying not to go POAS crazy lol, but do plan to retest Mon 6/8...
