Need reassurance, I feel so guilty

So had my first FET last week, natural with just progesterone pessaries as support. We transferred a 4AA embryo and everything was perfect, my lining was good, hormone levels all good etc. I (stupidly) started testing 5dp5dt and have been getting BFNs everyday since then on FRER. By day 8 I just knew it hadn't taken and stopped with the progesterone pessaries because I just hate them so much and I just knew deep down it hadn't worked. Now I'm 10dp5dt and I've started bleeding, but I'm having all this guilt and regret that I stopped my progesterone early, incase it was just that super late implantation. Im also freaking out and don't know what to tell my clinic incase they get mad at me for stopping the progesterone early.

Just feeling so exhausted and depressed by the whole process. Please don't come for me about stopping the pessaries, I already feel guilty enough.
