I was prescribed naproxen for back pain in November and took it for two months until the end of Dec. I wasn't told at the time, and in too much pain to read the small print but I've since read that it can affect fertility but not sure how.
During this time I was using an ovulation monitor. Before taking the naproxen I was 28 days cycle with peak LH at days 15/16 but then when I was taking naproxen (and after) I went to 26 days and peak at days 11/12. I've never not been 28 days.
Now 3 months on, I've returned to 28 days, but still 3 days early detecting a rise and peaking at days 12/13 and wondering if this is still the naproxen.
Has anyone else taken naproxen and noticed a change in cycle? And how long did any effects last?
