spotting 3-4 after cycle ended

Okay so I have been TTC for 3/4 months after having two miscarriages previously. I finished this months cycle on the 13th but then I had sex this morning. I'm off out tonight so got ready then when I wiped after having a wee there was some faint blood on the tissue and it was quite slippy (dischargy). Could this be anything as it was quite a few hours after sex, or could it just be a bit of period left over?
