I’m a single father and my daughter just had her first period…help me 😬

My (31m) wife, Kim died on Christmas of 2024 and we have three kids, Maddie 14, Jeremy 12, Jaycee 11. Maddie just….um got her period for the first time and I have no idea what to do. I don’t know what she needs or what to say to her. When Kim had her periods she would just say “I’m on my red spot” meaning no sex until she’s off. I never payed attention to what she buys or what she does for the cramps or ANYTHING. I have no feminine hygiene in the house and if I do it’s Kim’s stuff and I don’t know where she kept this stuff. I’ve checked bathrooms, closets, laundry rooms, etc nothing. My MIL and SIL passed away during the pandemic. It’s only me, my dad, and my brother (30). I’ve called to ask them and they don’t have any idea how to help Maddie. She’s the last girl. Like I said our immediate family is small. It’s just me, my dad, my brother, and my kids left. Then there’s “THE TALK” I have no idea what to say…all my dad said was how to make it feel good and not get her pregnant. My kids are homeschooled so if we ask about this situation to a teacher, counselor, or FEL it could get my kids either kicked out or suspended for asking an inappropriate and disrespectful question towards them.

Please help me. I’m very nervous about this stage but probably not as nervous as Maddie.

Edit: yes I know Christmas was like two weeks ago but I didn’t want anyone to be misguided by the dates so I put 2024 to make sure you got the date.

Update: I did what some of all advised me to do and I just sat her down and she said flat out “You have no idea what you’re doing.” I said “not on bit” we laughed (as someone suggested if I just made her laugh) I ordered some containers to store pads(someone mentioned they do that as well), tampons, condoms (as some suggested) etc. I bought her a heating pad (I had to see what kind my wife used so maybe it would’ve been good for Maddie) I got her some ibuprofen for her bathroom and in her purse. I still need to toughen up and go get her overnight panties (which I will do) and I will make sure she has a very comfy blanket and some relaxed clothing (as one suggested) I’m going to buy some more laundry cleaning stuff and I’m going to put it in a basket just for her to use just in case (as one said) and I’m gonna make sure she’s stocked up on snacks for each month. Thank you all!
