What tests should I get for irregular period, spotting and a sometimes too short luteal phase?

[Hao1]

Hi,

Going into month 6 of ttc and really find my cycle to be all over the place. Some months I have spotting for 5 days, others none. Sometimes the length is 27/29 days, others 25,31 and so on. Luteal phase changes, anything from 10(too short) to 12. Has anyone any advice for me on what tests to get?

I am so worried that something is wrong and I will never get my bfp.

Any advice appreciated.

@Hao1 Have you been tested for PCOS? Also low progesterone I think can cause a short luteal phase

How is PCOS test done?

Blood test and ultrasound

I would start taking vitamin B6. It's known to help with that

Hao1,
How are feeling? Did you find out the cause? Some of us experience this too.
