ok so I'm 17 weeks pregant and i just went to the bathroom after my boyfriend did .he took a shit and then i went pee.well when I went to go flush the toilet I looked it in it to make sure there was no blood .well there was this real dark thing. about the size of a dime maybe alittle bigger. I don't know what it was .I'm scared. it could be a piece of shit that was already in the toliet that didn't flush or it coukd be something else . any of u know what i should do?
