So it started two nights ago I’ve been at my boyfriends for 4 days now it started at night having the urge to pee a lot doesn’t burn when I pee just peeing a lot lots of pressure and now it’s still happening today and when I whiped there was a purple reddish mucus! Anyone know what this could be? Also we had sex on the 2nd of this month and he came in me 😩
