I've taken probably 10 wondfo's and at first they were coming up with vvfp almost invisible. But now they're getting darker. I've tested with the 88 cent Walmart test and it was positive as well but the frer are almost invisible and my digitalis say no. I tested my boyfriends urine 😂😂 lol to see if I had a bad batch and his was negative, also with water and still negative. I thought frer was supposed to be more sensitive. I have a doctors appointment to check my blood for hcg Monday but has this happened to anyone else? They can't all be false positives can they?
