weird cramping

ok so I wasn't sure where to post this, my last period was the 17th July this is my second month TTC, I have taken a hpt every week and all have been BFN, yesterday and today I have been having a strange cramping feeling sometimes it feels like it's in my right Overy area and sometimes it feels really low down, I never experience cramps not even when af is here, have any of you laddies experienced anything similar and gotten a BFP or could i be ovulating (the cramping only happens when I sit in weird positions or cough)
