Me and my boyfriend had unprotected sex seven days agothursdat the 9th.He went inside me.I don't recall any coming out.I started my period today the 17th.Its light an looks like red water.can I get or am I preganant?

So some comes out, that does not mean anything if it did or did not.

Next first day of period is hard to say, you can get a light period the first time and be pregnant. You can wait a couple weeks and try a pregnancy test

Is my period suppose to be watery?

Is my period suppose to be light n watery?
