To test or not to test?

Bee
Me and my partner have been ttc for 7 months just the natiral way since were both young ,25, no charts no kits just using no protection. With that being said i usually have a 38 day cycle, last month i was extremely stressed out going through a few horrible things and my period came two weeks early and only lasted 4 days but no cramps or clots just very light bleeding, it wasnt implanation i tested 3 weeks after just incase! How ever with it being SO light and early i figured i would either go back to normal or have a heavy one this month since all the stress was resilved last month ... Im going on cycle day 43 now and have had light cramps on and off for two weeks and diarrhea and loss of apetite the past week also creamy white discharge this past week... Should i test? I was gunna wait another few days but i cnt get it off my mind i just hate testing and getting a negative because it brings me down 😓😢
