I've been getting a lot of cramps for almost a week and I am not on my period or close to getting it just three days ago my vagina got tighter and it feels uncomfortable during sex WATS going on can I possibly be pregnant?

I don't think your vagina being tight has anything to do with being pregnant. Possibly your partner equates tight, with too dry, (thinking it is tight).

Either that or your post is way of base.

If you think you are pregnant, go to the doctor and have a test; to be perfectly sure. We can't tell you this from just one or two symptoms
