Flu like symptom 🤢

AF super late, all the signs but BFNs. I haven't tested in a few days. Doc requested blood work done but I kept putting it off. I was nauseous lastnight and awoken at 3am with horrible stomach cramps leading to diarrhea and my whole body is achey today. I didn't eat anything out of the ordinary. Did anyone else experience similar? I'm going to get blood work done this week.
