Help idk if I should retest

So I've been trying to conceive which feels like forever I might be over thinking again but two weeks Avon I started having cramping then the next two weeks lower back pain then next two was nausea and now my boobs have gotten bigger I took a test about a month ago and it was negative but my lower back is still hurting and I'm still nauseous I haven't had a period since February but the test a month ago was negative so I'm think about retesting but don't want to get another negative so I'm trying to see if anyone else thinks these are good symptoms of a positive
