Home LH urine tests
If you have irregular cycles, it may be difficult to know when you ovulate.
You can buy the clearblue fertility
monitor or opks (ovulation
predictor kits) at a pharmacy. Opks are located next to the condoms
usually. Follow the directions on the box. If your periods are very irregular (> 35day cycles) then you probably will need to use the clearblue monitor (link: http://bit.Ly/xwi55r ).
