As the two girls were walking over to Nancy's house Chris had his own problems because as soon as he got off the phone with Nancy she got some abdominal cramps and had to go to the bathroom.
When Chris got to the bathroom she sat down as she pulled down her panties only to see some blood on them "OH CRAP" she said as she know that the new Nancy body she had was starting her period.
When Chris finished she got so TP to put on her pussy until she found a pad in the bathroom cabinet.
After Chris got cleaned up she went downstairs to wait for Nancy to get there.
When Nancy and Tanya got there she did not know who was who until the one that looked like Tanya said "Lets get your chores over with so we can talk" At that point Chris figured that Nancy now looked like Tanya.
The girls could tell that Chris had something on his mind as they were doing the ironing.
When they got finished and went to Nancy's room Chris said "please tell me you brought the medallion so I can get out of this body."
Nancy said "What you hate my body that much."
Chris said "It's not that I thing the last time you had those shoes on you were starting your period because I had a problem a little bit ago but I was able to find a pad in the bathroom."
Tanya who looked like Mary said "OH no I don't think ether of you are going to like this but I did a search on the net for info on the medallion and it turns out the only thing that will stop it from working is if a woman is pregnant or on her period."
"WHAT" both Chris and Nancy said at the same time.
"SHHH" Tanya said "we don't want everyone in the house to know. This just means Chris is going to have to be you Nancy for a few day, then we can change you both back."
"It's not going to be that easy I just finished my period, what do you think my mom or sister are going to say if they find out Chris is on the rag." Nancy said.
"We don't have any other chose" Tanya said "we can't have two of you walking around Nancy we will just have to hope Chris can pull this off."
As the other two were talking Chris just sat there and then started to cry at what she herd.
Both Nancy and Tanya went over and hugged Chris "This is going to be alright we will get throw this."
As they sat there the 3 of them started to make plans.
