As I know you have to do the ghsul in the end of period so I checked online how to do the ghusl of janaba and Hayd together and some said you have to do the two ghusl differently.
If I need to do it differently which one should I do first or should I do one ghsul for janaba and hayd and to say thus as the niyyat I'm making ghsul to be clean from janaba and hayd
First ghusl must be done to regain tahrah (ritual purity) in order to be able to pray and worship. If a woman became junub during her menses. Even if she performed ghusl for Janabah she doesn't get in a state of tahrah unless by coincidence her menses ended.
So from a logical point of view ghusl (of Janabah) is not necesarry, but in case of a supposed haram (illegal) reason for this Janabah tawbah(repentance) is required. Nevertheless she might perform ghusl for Janabah during her menses. But it won't be a valid reason for being able to pray as her menses has not yet ended and praying during menses is haram (See for example: Do women need to check their menstruation before Fajr to see if they are required to also pray the previous night Isha?).
Otherwise if more than one reason for ghusl applies one could perform one ghusl for different purposes.
The matter of niyyah (intention) has been discussed and answered on the site before: it is not necessary nor more than permissible to utter it, as niyyah is in the heart. Further some scholars like the Hanafi school of fiqh and imam Sufyan a-Thawry say niyyah is neither required for ghusl nor wudu' nor any non pure worship. (See my answer on: Is niyyat for ghsul needed?)
As for how to perform ghusl this has also been answered on the site.
The same applies to the topic of menses and how to identify its ending. (See I have an period where the blood comes in small amounts; is it valid for me to fast or pray?)
this person is the same person who asked the question and I've checked a website and it says this
Question: A woman was in the state of Janabat and she realized that her monthly period had started. Can she perform one Ghusl later with the intention of both Ghusl-e Hayz and Ghusl-e Janabat?
Answer: Yes, one Ghusl is sufficient. It is permissible to perform one Ghusl with the intention of many obligatory Ghusl's such as Ghusl Haydh, Ghusl Janaba, Ghusl Nifas and Ghusl for touching a dead body. She can also perform the Ghusl Janaba whilst in the state of her monthly period, and then after its completion, she will need to perform the Ghusl of Haydh.
(So does the answer mean that I can perform ghusl of janabat while on period and I can perform ghusl of hayd when I finish my period) shia
