Hi @Kridik one of my closest friends has had 6 pregnancies and 4 live births but has never had a positive HPT. With every single pregnancy, she has had to keep demanding blood tests until one comes back positive. So, yes, it can happen. However, she's an anomaly!
In a few days, take another test - get good quality ones that detect low hCG like the FRE ones.
Whatever the outcome, put some pressure on your GP for assistance. They might be unwilling to do much until you've skipped more than 1 period, but the sooner you start hassling them, the sooner they'll take it seriously. Even at 41 days late, they'll say this is 1 missed period. 🙄
Also, just to be informed, check out the symptoms of early menopause. (Not that I'm saying it's that!!)
Unsure what the discharge means - everyone has had different things here. One of my first symptoms was extreme vaginal dryness. Now I have clear discharge and lots of it - started at about 9 weeks.
