Positive pregnancy test and then negative.

I started having symptoms like sore breasts, nausea and tired. I was also for like 4-5 days light spotting/bleeding with some brown. I wasn’t late but decided to test which was 10/27. I got a faint positive and was bawling! I had a miscarriage 4/23 and we have been trying ever since with no luck. Anyway I have tested a few times since then and it is a negative on different tests. My period was due 2 days ago and I have yet to start. I am so lost, hurt and confused as I have never got a positive test even a faint positive and not been actually pregnant. Has this happened to anyone else? I attached the test from 10/27 that was a faint positive.
