A little confused

This might be a little TMI but here it goes. I've been tracking my ovulation since the 17th and I haven't got one positive. I've also been tracking my cm. During the day my cm has been creamy. I woke up last night with my stomach hurting and went to the bathroom and had a bm. After wiping my cm looked all stringy like those pictures that shows your fertile. Well I to an opk this morning and it said no. I use the clear blue digital. I cant chexk my cm because we BD this morning so I dont think it would check right. Id be afraid it would be all him right now. Idk what's going on. What do you think?
