Sharing a pregnancy?!!

A little back story first....me and my sister in law are very close like we have been real sisters for years! She's like my best friend . She is 28. She has a daughter age 4 from a previous relationship. And she recently found the man of her dreams who we all LOVE they r planning to get married he also has two kids 12 and 15 who are very supportive and well behaved children. I am currently 12 weeks pregnant with my first. But lately my sister has been nauseous after eating and gasy. She told me last night she was a week late on her period . I told her I'm buying her a test today when she gets off work. I am SOOOOOOOOOO EXCITED!!!! I really hope she is pregnant and we can share this journey together ! I always wanted us to be pregnant at the same time! I have this feeling that she is pregnant I can just sense it and everytime I ask her she gets red so I think deep down she thinks she is too. I'm praying for two pink lines today!!! I'm beyond ecstatic😍😍😍😍💙❤💙❤💙❤🚼👶
