when should I test??

Marie
Ok so.. I had a late miscarriage in June and trying again but been recording my cycle in the ap.. I did not have a period till July after the miscarriage ( understandably this is not abnormal) but since then I have been getting regular monthly cycles but days in between have been reducing.. august cycle was 33 days, sept 30 days, October 27 days and today in November I am now at 30 days... I did a test 4 days ago (. Know it could if been to early that was negative). Just would like to know what people thoughts were.. I feel like I have pregnancy symptoms.. but that could be my body playing tricks on me.. and with my late miscarriage was not aware I was pregnant till 10 weeks so I have nothing to compare it to.. what is everyone's thoughts.. thank you for anyone that reads and replies
