Late AF.. PLS HELP. Read below for info

I have a regular 28 day cycle my partner and I have been trying to conceive for 18 months. I had been using ovulation kits all month they were all faded 2nd lines right up till 7 days before my period I got 3 tests dark lines. I am now 6 days late have really sore and heavy breasts, mild cramps, loss of appetite, higher temp at night around 37.0 degrees.. hot flashes, extremely fatigue and drained but trouble sleeping, a hell of a lot of clear watery discharge. I took a pregnancy test yesterday morning (slept for 10 hours) got a faint 2nd line straight away) but this morning got 2 negatives (5 hours sleep) & still negative this afternoon. The confusion is giving me so many mixed emotions and making me depressed. Also my doctor took tests on day 21 of my cycle and said I didn’t even ovulate. but it could it be that I ovulated later in the cycle?? I tried to get an appointment for bloods but can’t get in until the 7th and the waits messing me up really bad already. Anyone with similar experiences n what happened with you? Please I’m crying out for help 😥
