Congrats Beachy!!!!
It is totally normal to not have symptoms so early.
I honestly think these tests are as good or better than FRER and personally wouldn't waste the money - go for a digi in a few days if you want confirmation.
Beachy - haven't been pregnant before but love coffee so researched this extensively.
It is considered safe to have up to 200mg of caffeine a day. For me that is up to 3 small regular nespresso shots (195mg) but it can also mean 2 small cups of coffee or one large. As far as decaf you have to be careful - some coffees are decaffeinated using a chemical process that is no bueno when preg. Nespresso uses a chemical-free process. Some companies say they use a "water process" which sounds safe but frequently still actually involves chemicals. Look online for your brand or call the company.
