False Positive?

Hi ladies 👋🏾 This is my first post! 😱 Me and my husband have been trying for about 2 years. We finally got our BFP in January but miscarried in February. We’ve been trying since then. Currently in the tww. AF is supposed to come tomorrow. From 10-12 DPO I’ve been testing with the cheapies and all came out negative. But I was taking the bathroom trash out this morning and this one fell out with the slightest faint line! I tried to test again this morning but I pushed out a teaspoon of urine because I already went 🤷🏾‍♀️😂 it was enough to fill the dropper but that came out negative 😕 After getting all these negatives lately, me and my husband decided to take a break mentally and physically because ttc is not easy for everyone so we just wanna get right and try again. Now that my mind was set on taking a break, this has me concerned and possibly changing my mind..again!
