Hi ladies, this is my very first time tracking ovulation with strips. My cycles can vary from about 35 - 39 days. Currently on cd18, strips arrived this morning and these are my first 2 test results according to premom. Just need some advice please- as the lines are pretty strong does this mean ovulation is imminent and how often should I be dtd from now? Also, what does the peak then high mean? Thought my fertile window was next week so feel a bit surpised! Thanks in advance x
