TWW and some MORE spotting? HELP!!!

Bree • I`m 27 yrs old and have one son (8). I just had our second. Not sure if we're done or not.
So I thought a couple of days ago I had some IB (TTC ) which would have put me at 6dpo but I randomly had more today probably about 3 drops (sorry no pic straight to the washer) and it brown in color. It's been 7yrs since the first (which was a big whoops) AF not due until Monday (according to Glow) ADVICE! HELP! PLEEEASE! Its only our first month offically TTC (after the scary first pregnancy and him having cleft lip and palate) I want to make sure nothing is wrong.? I don't think I could forgive myself if something happened this time. I need some one anyone. Please.
