FREAKYYYYY

So my bday is July 23. My older sisters bday is July 13.. Well I told her Christmas eve I was pregnant and that my due date was July 23. Then, she told the whole family SHE is pregnant and her due date is July 13! Of all the days! She and her husband have the same birthday too. Now my birthday was her due date when our mom was pregnant. And my in laws got engaged on July 23 and my husband's grandfather also shares the July 13th birthday. If all this isn't a sign then idk what is!!
