So last night my sister called me crying because she felt like she was having contractions about to have a baby but she not pregnant I'm the one that's 36 weeks pregnant . My mother told me when my twin sister was pregnant 2 years ago I felt sick when she was about to have her baby! But last night I felt fine no contractions or anything can this mean I can go into labor if my sister feeling the pain but I'm not?? She told me the pain stopped

It is well known that twins often feel and experience very similar things even when apart.
I wouldn't conclude, however, that if she is feeling contractions and you aren't, that that means that her body is telling you something about your body. You can't really separate 'something going on between twins' and total coincidence if it turns out that you are about to give birth. If all signs are that you are going to give birth any day now, it seems reasonable to think that she is anticipating the event right along with you. But that's about it - lots of sympathetic sensations.

When you will go into labor, is not known, but yes, twins are known to experience each others pain. ** you did not remember being sick, when sister pregnant?
