Super faint line 🤷🏻‍♀️

So I had a stillbirth back in May and had decided to officially start trying in September. I’ve been pregnant 5 times (1 live birth/she’s 2) and all have shown up on a test 4-5 days BEFORE my period is due except for my 2 year old she was super late to show. Anyway, I’ve taken a few tests all neg. Tuesday morning I took one and it was super faint (took forever to show up) but it’s thicker in person than it is in the picture. Much more prominent. The camera does a really bad job at capturing the line lol. Next morning negative test. I am now 4 days late with AF and got another negative this morning (digital). I am as of today (Thursday) 17 dpo 🤷🏻‍♀️ I have had some discharge here and there and have spotted maybe twice but Brown and very little. I’ve never had this happen. I literally never miss my period. If I’m late it’s like I’m due Sunday and get it Sunday at 11:55pm kind of late. I’m in a hurry to either get a BFP or my AF so I can either celebrate or get back to trying ASAP. Anyone have any sort of similar experience? I also have APS so I need to start my injections as soon as bfp shows so that makes me a serial tester.
