Thanks sotiredmama. Spotting stopped for now. Gonna pop to GP next week. I'm in London and the hospitals get Very busy so best to get US scheduled sooner rather than later.
Glad your spotting has stopped! Sounds like implanttaion spotting... that would explain why your test is still very light as implantation would have literally happened a couple of days ago.
Do you mean your 12 week ultrasound? Or would you be having one earlier?
Unfortunately, I'd be very surprised if a GP would prescribe supplemental progesterone... it seems to be so rarely done here, and when it is, it's through a fertility specialist. Is there a reason you think you need it? With your levels being so high last cycle, it really doesn't sound like you have a low progesterone issue, so try not to worry.
I won't be seeing my GP at all pregnancy-wise... just straight to midwife. Worth calling your surgery and seeing what procedure is with you... some surgeries like you to see the GP first and some say just to book straight with the midwife... normally booking appointments are for 8-10 weeks. Your midwife is usually the one to arrange your 12 week scan.
Would recommend maybe waiting a day or two then testing again with a FRER in the morning - the odds are the line will be a lot stronger. Digis can be very stressful, so if you can, consider making this your first and last.
Congratulations again!
