Period or not ... should i be worried?

Shaynon
My husband and I have been ttc since feb. Of this year. Im 35 and hes 33. All tests have come back negative. This past Saturday I was 8 days late and tested. Negative again. A few hours after I had a gush of orangish blood that lightened to nothing within the hour. Sunday I had a gush with one clot and the it again lightened to nothing. Monday nothing and Tuesday a spot or two of pinkish clear goo. I don't know whether to log this as my period or hope it's implantation. .or is it something else. Help is appreciated. Thank you!
