helppppp!

TTC actively for around 10 months, have PCOS
Had sex on Saturday night (6th), constant cramping today and little brownish stuff once when wiping today...could this be anything? 
Not too sure if I was ovulating due to PCOS...😭
Definitely not due a period as had one around 3 weeks ago and before that is was September 2016 so don't think I'm due one anytime soon as I am suppper irregular...😩
