When is the appropriate time to take a DUTCH test to check my hormone level?

Yes I would suggest to have it checked. If you are having cycles every 2-3 months, there is a good chance you’re not ovulating consistently. Common causes of not ovulating regularly (anovulation) include: Polycystic ovarian syndrome Thyroid disorders in particular hypothyroidism Rare disorders of the pituitary gland like hyperprolactinemia It is useful coming to a diagnosis because chronic anovulation can result in hyperplasia of the endometrium (too much growth and thickening of your womb lining). Anovulation will also result in some difficulty in conceiving.

Thanks for the very clear history and photographs. The red rash looks like a bruise and this is likely to be due to excessive pressure over the area, aggravated by the compression from the stripes which squeezes the enclosed areas. This will typically take 1 to 2 weeks to resolve. Blood tests are usually done to rule out underlying conditions like low platelets which may lead to increased susceptibilty to bleeding. I assume these tests were done and were normal. I would suggest wearing leotards without this stripe pattern so that there will not be added pressure to the skin.
