ttc still waiting !!

Hello this is my first time posting. I've been ttc for a few months now and I get nervous and anxious thinking something is wrong with me every time my 2ww is up and no luck. I think I'm just not timing it right. I've been having bloating pains in my abdomen this morning and a slight headache. I'm not sure if it's pre ovulation or ovulation. Should I try my luck tonight to be sure or is it too late ??
