Ugh!!!!

So I had a faint but definitely there positive test yesterday morning. Took another one first thing this morning (I know it doubles every 48 hours) but was hoping it would be at least the same as the first but it was definitely stark white. Has anyone had a faint positive then nothing and still was pregnant?? I’ll test again in a couple of days. I am still 4 days early. Really trying to not get my hopes up. Trying 3 years and had 1 miscarriage at 9 weeks this past summer and was really hoping this was our rainbow baby!

So confused!!! Ugh!!!
