Unsure if I’m pregnant

Hey all, so I noticed some spotting at first for about 2 days. Cramping and bloating with no period.... 2 negative pregancy test early on, havent tested since because I didnt think i was pregnant after that. It’s now the 4th week spotting but still no period. Also experincing tiredness which of course I think is nothing. Also, never been pregnant. What are your thoughts?
