Bfp at 8DPO then nothing ?!? Help needed

[glitterbomb13]

Hi all I have a 33 cycle and ovulate roughly on cd17. On CD24 I was feeling a bit randomly dizzy and weird so first thing on CD25 which would be 8DPO I woke up and did 2 IC with fmu very faint lines on both , saved the FMU and popped out to the shops to get some FRERs came home in the afternoon did another sample and did another 2 IC again faint but visable lines so did the FRER using the FMU sample and it was totally negative . The next day I did another FRER with FMU and was totally neg so have all other IC so far. Problem is I have a progesterone problem so I have to start using cyclogest pesseries as soon as I get a
BFP which I did do the night with the IC bfp. I have had really bad cramps for 1.5 weeks now and on occasion felt sicky but no sore boobs etc. So today at 11DPO still getting negs and AF due on Tuesday of next week . So my question is could this have been a conception / implantation surge and I still could have a credible BFP? Or am I out and kidding myself ?!? I just don't know what to do regarding the pesseries keep going or not ? X

To be honest if you never got a positive on FRER, which are as sensitive and false-line-proof a test as you can buy in general, I would mistrust the cheapies (which have a lower sensitivity and are much more prone to dye runs, evap lines etc) and say you didn't actually have HCG in your system. If you had a viable ongoing pregnancy it would have shown up on FRER and got darker by the day.

I would stop the pessaries and await your period.
