Anyone?

So even with having pcos I have always been very in touch with my body and I know that it should be impossible but I’m 4 dpo and I’m so nauseous and crampy it’s insane. Trying to brush it off and think well maybe I didn’t sleep enough or maybe I’m stressed out or maybe I didn’t eat enough but something in my mind is just telling me that is not the case well at least 10 to 14 days maybe I will know something or maybe not but any one else just have a solid feeling after ovulation and it be right??
