Any of these symptoms been a good sign for anyone? Yesterday at roughly 7dpo I felt absolutely fine until about 7pm when I suddenly felt very dizzy and developed a really intense headache. Headache continued through the night and I felt hungover this morning. I felt warm and nauseous on my way to work until I had something to eat but dull headache is still there this evening and I honestly feel quite hungover, although Ibe not touched any alcohol, and (sorry for this part) I'm soooo gassy and have been for a few days now. I'm not one fir symptom spotting but these particular symptoms have been quite irritating.
