Hi Irritability may be due to implant because of this complaint is expected events when insertion. Do have only this complaint or like over bleeding, wt gain, head ache, increse blood pressure level Kindly ruled out or get opinion from experts (have child or affect pregnancy in future) Because this complaint due to implant. (It releases small quantity levels of hormones) Aswagantha is good medication for stress &mood irritability, Insomnia also. May i suggest add m2tone syrup 10ml two times per day along with Aswagantha.

You can take Ashwagandha for stress relief,from Himalaya 1 tab twice daily for 3 months. Other habits ,you have not mentioned. Better avoid spicy oily tamarind nonveg items

Good morning mam, In my opinion if you don't have any physical compleint like irregular menses,pain in pelvic region ,weight change with your mental compleint then it's not to worry.   Ashwgandha is general tonic use as stress deliver and settle over palpitation.so you can use it.
