I'm freaking out. while on my cruise I went to the bathroom and there was a small trace of blood. I got so scared I thought I was losing the baby so I took it easy for a while. well my man and I just got done being down and dirty...if you catch my drift...and I went pee again and while there was no blood there was a pale pink stain. what do I do?!?!?!?!
