TWW and 4 days to af

Hi everyone. This is my first post. My husband and I have been trying for 7 months. I was diagnosed with PCOS. This is my 5th cycle of ovidrel and leteozole. I had an HSG done this cycle and now I’m in the TWW. Glow says I’m due for af in 4 days but I feel like it’s usually longer cycle so about 6 days. I’ve been feeling tired, bloated and this time a dull tail bone pain. Do you think it could be early pregnancy symptoms? Anyone have these symptoms during the TWW and get a bfp? Also do you think I should take the early pregnancy test tomorrow or wait longer? Thank you all for the help. This process is tough and it’s helpful to know there are others with similar issues that are TTC
