If your goal is to identify your fertile window or pinpoint ovulation, there are several good options. The best choice depends on whether you’re trying to conceive, avoid pregnancy, or simply understand your cycle.

Method	What it detects	Best for	Main limitation
Urine LH ovulation tests	LH surge ~1–2 days before ovulation	Predicting upcoming ovulation	Can give false positives/negatives; less reliable with some conditions such as PCOS
Cervical mucus tracking	Estrogen-related changes in vaginal/cervical mucus	Low-cost, hormone-free tracking	Requires learning what your mucus patterns mean
Basal body temperature (BBT)	Temperature rise after ovulation	Confirming that ovulation likely occurred	Usually confirms ovulation after it happens rather than predicting it
Fertility monitors	Often LH + estrogen metabolites	More automated tracking	More expensive; still predicts rather than directly observing ovulation
Cycle-tracking apps	Calendar/cycle patterns	Recording cycles and combining other measurements	Calendar-only prediction can be substantially inaccurate for the exact ovulation day
Blood progesterone test	Post-ovulation progesterone	Clinically confirming ovulation	Requires appropriately timed testing; generally used when medically indicated
Ultrasound monitoring	Follicle development/ovulation	Fertility evaluation or treatment	Requires a clinician and is not practical for routine home tracking

What I'd consider for most people

1. LH strips + cervical mucus
A particularly practical combination if you're trying to conceive. LH tests detect the hormonal surge that generally precedes ovulation by about 1–1½ days, while cervical mucus gives you another indication that you're approaching the fertile window.

2. LH strips + BBT
Useful if you want both prediction and confirmation: LH helps identify that ovulation is approaching, while BBT can show that the temperature shift associated with ovulation has occurred.

3. A fertility monitor
Worth considering if you want less manual interpretation. Some devices measure both LH and estrogen metabolites, giving more information about the fertile window than a simple calendar app.

One important distinction: an LH test doesn't prove that ovulation actually occurred—it detects the hormonal surge that normally precedes it. If you need to establish whether you're ovulating, a clinician can use appropriately timed progesterone testing and/or ultrasound.

If you tell me whether you're trying to conceive, trying to avoid pregnancy, or just tracking your cycle, I can narrow this down to the most appropriate methods and specific products/apps currently available.
