Weird symptoms!!

Sana

I'm currently 10 dpiui (<a href="https://glowing.com/glow-fertility-program">IUI</a>#3) . I had 2 dominant follicles 20mm and 18mm in my left ovary when I was triggered 5000iu HCG shot. We did <a href="https://glowing.com/glow-fertility-program">IUI</a> on cd14. From 2 dpiui I started taking progesterone 400 mg vaginally. I tested out my trigger in 7dpiui. On 7 dpiui I had brown spots on panty liner. I had implantation with my first pregnancy on 6dpo and got a positive on 11 dpo. Although I'm not trying to symptom spot this cycle and relax. I have some weird symptoms this cycle. From 8 dpiui my symptoms are intense, I feel feverish but temp is just 98-99. Suddenly hot flashes, indigestion, nausea and diarrhea. But, I am not sick because I have these symptoms from last 3 days like every few hours and I'm fine again. But, still I don't have any hopes because this will be our last <a href="https://glowing.com/glow-fertility-program">iui</a> and are going to start <a href="https://glowing.com/glow-fertility-program">ivf</a> next cycle. But, symptoms are really weird. Could these be because of progesterone?
