I'm about 4dpo and I woke up with mild cramps this morning. This after noon at 2 different times hours apart I got a thick glob of ewcm kind of tinted cream or light yellow. It's not slippery like ewcm.. it's more thick like jelly. Internally is creamy cm. I took an opk just to see if i was completely wrong but it was stark white. Not even the usual faint pink. I also had some lower back pain for a few minutes this evening. Anyone had this before a bfp?
