AL-MAHAIZ IS NOT MENSTRUATION
2:222 - وَيَسْأَلُونَكَ عَنِ الْمَحِيضِ ۖ قُلْ هُوَ أَذًى فَاعْتَزِلُوا النِّسَاءَ فِي الْمَحِيضِ ۖ وَلَا تَقْرَبُوهُنَّ حَتَّىٰ يَطْهُرْنَ ۖ فَإِذَا تَطَهَّرْنَ فَأْتُوهُنَّ مِنْ حَيْثُ أَمَرَكُمُ اللَّهُ ۚ إِنَّ اللَّهَ يُحِبُّ التَّوَّابِينَ وَيُحِبُّ الْمُتَطَهِّرِينَ
And they ask you about what the period / moment of flow of thought [الْمَحِيضِ]? Say, "It is a stress / pressure [which compels to do things against our own will], so keep away from the desire / urges [النِّسَاءَ] during the strong flow of thoughts. And do not be close to them [urges] until they are pure. And if they have purified themselves, then yield to them from where Allah [system of consciousness] has ordained you. Indeed, Allah loves those who are constantly repentant and loves those who purify themselves."
الْمَحِيضِ - flow of urges, desire after maturity / puberty, age when the urges, desire need to be controlled, torrent overflowed or poured out - The triliteral root of الْمَحِيضِ - is ḥā yā ḍād (ح ي ض) occurs four times in the entire Quran, in two derived forms:
once as the form I verb yaḥiḍ (يَحِضْ)
three times as the passive participle maḥīḍ (مَحِيض)
The words تَطَهَّرْنَ and الْمُتَطَهِّرِينَ relate to mental purity rather than physical cleanliness.

2:223 - نِسَاؤُكُمْ حَرْثٌ لَّكُمْ فَأْتُوا حَرْثَكُمْ أَنَّىٰ شِئْتُمْ ۖ وَقَدِّمُوا لِأَنفُسِكُمْ ۚ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّكُم مُّلَاقُوهُ ۗ وَبَشِّرِ الْمُؤْمِنِينَ
Your urges are a fields for sowing seed for you, so come to your place of cultivation however you wish to put forth [righteousness] for your souls [Nafs]. And be thoughtful of Allah [system of consciousness] and know that you will meet Him. And be sensible to those [thoughts] who believers (thoughts that believe).
Our urges, desires are like ploughs which cultivate our lower consciousness before sowing seeds in it, that's why it is compared to fertile field for sowing seeds which are bound to grow and help us in reaching our aspirations or meeting our goals.
