All out if whack!

Hubby and I are trying to conceive after our miscarriage and also believed to have had a chemical pregnancy after that. I am normally a 27 day cycle. I had an LH surge on digital test 5/31 and should have gotten my cycle on 6/17. Well, cycle didn't start then. Hubby was convenced I was pregnant because I started peeing about once an hour ( no pain) and really tired (both things I experienced in first pregnancy and he said acting unlike myself. For several days before I should have had my period I had weird pains, low in my groin and burning feeling in my lower back, also not my common, dull AF cramps. Meanwhile I've been taking a store full of tests all BFNs.
So today I finally started spotting, 3 days late and it was a funny rust color for most of the day and some brown, but now has seemed to have stopped already. I really think it's too late in my cycle for implantation bleeding so no idea what's going in. The pain I had has eased up some. 
I was worried about an etopic pregnancy as I only have one tube/ ovary left due to tumor (same side as pain) but I have yet to get a postive on home test so not sure if that could be it or if I should still test Postitive if that is the cause.
Anyone experience anything like this? Ideas?
