A few things come to mind:
- progesterone converts to neurosteroids (i.e. allopregnanolone) which rise and fall rapidly when taken orally. These neurosteroids are believed to reduce anxiety, make us feel calmer, more relaxed, happier. The fall could result in irritability/edginess. A study found that combining progesterone with a high dose of dutasteride prevented this as probably neurosteroid levels remained low and
constant.
- high estrogen (?): in one study in ciswomen, high levels (above 150 pg/ml) were found to trigger anxiety/irritability/aggression. The addition of progesterone in these women cancelled that effect but the dose was higher than typically prescribed in us and was only taken 10 days every month.
- do you take your progesterone continuously or cyclically? If the latter, then this could perhaps account for the "testiness".
- progesterone is anti-estrogenic, reducing tissue sensitivity to estrogen so perhaps this could be the reason as estrogen in some women actually seems to have a "calming" effect.
- T is too low (?): even in women, too little T may cause anxiety despite good levels of E2.
If ciswomen are testy, it's likely because of their hormonal fluctuations which we don't experience to the same degree because our levels are usually more stable.
These are just possibilities I'm raising but that you should bring up with your doctor and discuss in more detail. I ain't the expert here.

Good luck.
