26 days late with no AF

I am now currently 26 days late to date and have taken loads of pregnancy tests and all came back negative apart from 2 what we saw as vvvfls, I have numerous pregnancy symptoms aswell such as creamy discharge, headaches, nausea, funny pain in nipples. I was currently taking loestrin 30 for 6 months and then had to change over to desogesterol due to headaches and blood pressure. I stopped my pill on the 25th of August after taking the first few pills very sporadically, I never completed taking the pill 7 days straight to ensure I was protected against pregnancy. Me and my SO have been trying since having sex pretty much every other day. I went for a blood test last week and on my results sheet it says original result 5 iu/l so I assume I do have some hcg in me but the reception told me my result was negative. I have a small simple cyst on my left ovary aswell.

Is there anyone out there who has been in my situation of a really late period and negative tests and then turned put pregnant? I hate not knowing wether I am or not. I just want some advice really.

Thanks ladies x
