TMI!!!! Implantation bleeding help!

Laura

Hiya! I’m TTC baby number one and me and partner have been trying since March, I have endo so know it’s going to be a lot harder. 6/7 DPO I had a very light tinge of pink with watery discharge when I wiped, then a small amount of brown the following day then all disappeared. This was at cycle day 23/24 and my cycles are between 32-36 days long! I’ve never had any mid cycle spotting before and it’s way to early to be my period and it’s now stopped! Also last three days I have had awful nausea and fatigue until around 3pm and have just been going back to bed then when I wake up around 3-4pm felt absolutely fine and vomited yesterday, then again this evening when I smelt a pile of sick from a patient (I’m a nurse but smells never usually bother me), am I over thinking things or could this be it? When should I test again I tested yesterday and was clear negative I’m 9DPO so was it too early? I’ve attached a picture of my slight spotting! Any advice please will be welcomed.

Thank you!!!
