Having to wait another 7 days for answers 😭 after I have already waited 5 days after I was due!!!

Hi, I was wondering if someone would be able to help me out. On March 6th I was 12DPO and got this result on a pregnancy test.

On March 8th i was due on and I got this result, both showing faint lines however Thursdays seems darker to me (maybe just me)

March 8th (Thursday) Afternoon i had an infertility appointment (because of how long I’ve been trying and how many miscarriages I have had) and they did a test at the hospital using a machine it apparently showed an error code 5 times before giving a negative result.

March 9th (Friday) morning I went to the doctors to find out what’s going on, he did a pregnancy test and didn’t even wait a full minute to read the results before telling me it was negative and discarding the test. I came home and went to do a pregnancy test (with the same urine he tested) but did an ovulation one by accident 🤦‍♀️ then I did a pregnancy test too, where is what I got...

Also I thought I may add the doctor I saw said he wouldn’t do a blood test as it was a waste of NHS money... I feel very let down to say the least.

I had a doctors appointment again today with my normal doctor and feel a big more at ease he is slowly taking me off some medication as it could be hiding the hormones, he also said unfortunately I have to wait a week before he can send me for a blood test as the lab will most lightly send it back, when he does send off for it in a weeks time he will also put a few other test in to find out why I am late if I am not pregnant. I took this before going to the doctors

I am so confused and I am 5 days late, i have what seem like pregnancy symptoms, going off different foods, some smells or tastes making me sick, backache, hot flushes. (Also my partner says when we have sex it feels like I am a lot smaller inside, as if it is swollen) I also had very light spotting 5DPO if anyone had any idea what’s happening people say so!!!
