7dpo is crazy early.... I know a lot of you like to start early, and it's fine if it's for fun. But don't get discouraged when it's so early! I see most women get a nice clear bfp at 10dpo and nothing clear before! I didn't even get my own bfp before 10dpo myself, and I recently saw one woman only get hers at around 15dpo!
I don't know if you have had children before and are thinking "Well last time I had it that early!" like some women do, but remember that all pregnancies are different. One women might get super lucky and get what I call a "rare early positive" at 7dpo, but in most cases, it doesn't happen. It's rare to happen.
If you enjoy poas, go for it! But don't give up when you're not even in the normal range for expected positives.
The normal range to expect a positive is not before 9dpo. And even 9dpo is pushing it for some.
I first started testing at 8dpo, stark white, totally crushing. Then 10dpo, I get a positive IC, frer AND digi. It shows what waiting for the right time to test can do!
