PMOS Awareness Month is a chance to talk about something that can be particularly confusing when you’re trying to understand your cycle: ovulation.
If you have PMOS (formerly PCOS), ovulation predictor kits can sometimes be harder to interpret.
These tests measure a rise in luteinising hormone (LH), which usually happens before ovulation. A positive result can suggest that ovulation may be approaching, although it can’t confirm that an egg was actually released.
With PMOS, hormone patterns can be less predictable. Some people may see repeated positive results (high-ish LH levels) or find it difficult to identify a clear LH surge.
If you’re unsure whether you’re ovulating, your fertility specialist can look at your cycle in more detail. Depending on your situation, blood tests or ultrasound monitoring can help us understand whether and when ovulation is happening.
This PMOS Awareness Month, getting to know what your cycle is doing can be a useful place to start 💜
