12dpiui ...bfp?

Ladies, help! I don't want to believe this. We've been TTC for over 5 years with 2 miscarriages (one natural cycle, the other clomid only) and had numerous failed medicated cycles and a failed IUI. Our second IUI a few weeks ago didn't give me much hope, and I have been expecting it to fail and just take a break til the spring. I was testing out my trigger and haven't gotten a bfn since I starting testing at 5pdiui (with dollar store cheapies). Today is 12dpiui, and I tested yesterday and today with FRER and I am praying it's no longer my trigger. Please give me your options!
