Long cycles/short periods

Louise

Hi ladies

We have been TTC for 15 months. In that time

My shortest cycles was 33 days (2 cycles ago) and longest 69 (ugh). With a PCOS diagnosis, accupunture and supplements most common seems around 38-42 days. However my period which was always light when on birth control is now very max 3 days long, and even on day 3 just brown spotting. Is this normal???

Had a progesterone test this cycle but LF (from BBT) is always 14-15 days.

Any help appreciated xx
