I might be in trouble here.. 😪

Maggie
I'm 17, 
And my boyfriend and I had sex on the 2nd October and I'm meant to get my period on the 10th, I know it's early days, but I've taken the morning after pill (4th) on the Sunday, but I've been feeling sick and not being able to eat right, but I've also get hip pains which for me are a sign of getting my period, but my friend is worried, but my boyfriend isn't, and I'm stuck in the middle, should I do a test to be sure? Or what?Â
