Really hoping you get your BFP soon OP 
We weren’t trying to conceive at the time that I got my BFP. I thought I was getting my period as I’d started spotting quite a bit (turns out I had a small bleed by the placenta, completely normal and disappeared after a few weeks).
When my period still hadn’t arrived DP went out to get a CB digital test. However, all of our local supermarkets were sold out! DP went to 5 different stores and in the end got an Asda own brand digital.
Took the test and got a positive which I didn’t believe. Quickly did a google and Asda’s own pregnancy tests are notoriously untrustworthy. So we went further afield to find a CB test.
Took that and got our BFP. I remember just feeling an immense shift in myself and the weight of the responsibility of what we were about to do. I was in disbelief.
We spoke for hours after, about how we couldn’t believe that all that was happening in my belly right then. I too also thought about all the other women who have gotten a BFP, the queen, my mum etc. It was so surreal.
The excitement kicked in very quickly later that day and we both flitted between terror and elation. It was an intense time but so very lovely.
LO is now 9 weeks old.
Wishing you lots of luck OP
