I’ve never had bad test from these before ever at least i don’t think i have. I recently had a miscarriage. It will be a month Thursday from when it started. I was 6 1/2 weeks. I’ve been using these to test out my hcg from my system. These are the same test i used when i found out i was pregnant as well. Well i ordered 2 boxes and one of them give me negatives and the other gives me positives. The one that gives me positives expires in the year 2024. The ones that give me negatives expire 2023. Sucks cause i don’t know which is right. I’ll have to buy a dif brand i guess to see which ones are right. Have any of you had a bad batch that were incorrect lately?tia😊
