So me and my hubby have been ttc since October no luck as yet I came off my pill the end of September. Been tracking cm so far had ewcm most months last month didnt have any. So I thought this month I would use opk's and temperature charts. My last period started the 27th of Jan and ended the 31st of Jan. When should I start using opk's and temperature charting? Also anyone have any advice to boost our chances?
