Advice please may be tmi

Hi. I am according to glow 10 dpo. I started having slight nausea, sore tender breasts, headaches, dizziness, constipation, and slight mood swings about 3/4 dpo. ( I've been told pregnancy symptoms can't come that early but I've already had an angel baby and two more babies. I know my body and yes it is possible.) At 8 dpo I had some light pink on the tp when I wiped and went to a brown cm and back and forth. Then at 9 dpo had that and a reddish one on tp. Never anything more than just wiping. And have been having menstrual like cramps. Af is due on the 20th and I have always had a 29 day cycle very regular with af lasting 5 days. But we are trying so we have been following the calender. I got a bfn yesterday and today even though with tweaking some say they can see a super tiny line. But I don't see anything. I'm also darn near blind and have no clue where my glasses are lol. What do you guys think?
