Hi, I’m posting this as I think that someone, somewhere will find it helpful, during their 3am internet scour whilst feeling crazy having broken into another hpt, or ordered more tests on amazon, not sure if they tested too early or had a biochemical (again). This time I did ALL the hpt testing possible and it’s is really a story about the pointlessness of early testing after trigger shots, mixing tests, and breaking into digitals.
I’m TTC through IVF and have previously either tested out my trigger with internet cheapies like mommed, or used a digital test at day 10 after 250mcg ovitrelle. (About 3 days after embryo transfer). I normally then crack a few days later and test early, using FRER or another ‘early’ test. Bad idea! Switching from a 25 unit HCG test to a more sensitive one after a few days is possibly going to give you wonky data that looks like a biochemical.
This cycle was 100% bfn (photos). Last time tested early and had a confusing blue dye test result, ended up buying and cracking open digitals, watching women test their husband’s pee on youtube etc. The full crazy.
This time I used the 10 unit HCG clearblue ultra early digital (the costly red flashing light one) on day 10 post trigger and official testing day. No one seems to have broken into this one on youtube yet, but it has two readers and yet only shows one line. The lines looked pretty similar when I was definitively HCG positive and negative, so maybe it’s the control line. Either way, ignore it. Read the display, crack it open to recycle it but forget the testing strip.
In addition, I made the expensive (but I’m only doing this once) decision to test out my trigger shot this time using FRER. FRER captures HCG at almost 6 units HCG I think. Anyway, lo and behold rather than my trigger shot being out by day 10, it was really taking the whole 14 days to really become (incontrovertibly, not even worth holding up to the light, nothing there at 10 mins) undetectable.
I’m so done with this. I’ll do the flashy digital on official testing day from now on.
Tl;dr: the flashing red LED clearblue ultra early digital test tells you nothing if you crack into it.
Maybe don’t mix and match tests when testing out trigger/early testing. My trigger shot lasted much longer than I thought.
