Help!!

Kirsten • Im Kirsten, & I'm a mommy to Jazmyne

Its been 6 mths since I've had sex with my partner..

Well, when we did it earlier this morning, it hurt a bit & after he finished I started to bleed a little bit. Not heavy, but enough that I put a pad in my undies in case!

I think sex triggered my period as I haven't had it yet this month, any opinions what it could be??
