Jasmine, I still get faint positives 7 days after a 1500iu pregnyl booster shot (haven't tested later than that), but we all metabolise the hcg at different rates... I use ICs when I test out the pregnyl, but the FRER will work just as well (just cost more). If you want to save some money, you could wait a few days before you start testing and you'd normally test daily. Or you could just start testing 3-4 days before your b/t. If you don't get any negatives, what you're looking for is the test line getting progressively darker (BFP) instead of lighter (BFN)...
