If they aren’t a sign of anything, why are women saying that the dates went up as expected with their healthy pregnancies and stayed at 1-2 or 2-3 the time they had an mc??
Look at the HCG levels that they use. Its' for entertainment, they've said so themselves, the 2 - 3 levels covers normal HCG levels for a lot of weeks. It's luck of the drawer.
I don't think I ever saw 3+ and I'm nearly 29 weeks now. I can't remember at what point I took the last one, though - my doctor was clear that they don't help, and neither do early dating scans, and I was just increasing my own anxiety which wasn't good for the baby.
For what it's worth, the dating seems sketchy throughout. My early scans put me at 8 weeks when my LMP had me at 7. At my 12 week scan, they moved me back 10 days. At 20 weeks, baby measured 6 days ahead, but they don't change EDD after 12 weeks. At my 28 week scan, baby measured 30 weeks.
I was trying to provide some reassurance that even Clearblue have said that these aren't medical; they are for entertainment, and not to repeatedly use them. It's up to you if you do, but I regret stressing so much about various things during this pregnancy - this being one of them.
Best of luck to you both
