TWW and indigestion

I had a positive opk on 10/6 with ovulation either 10/6 or 10/7. So I’m 7-8 DPO. I have intense indigestion that started yesterday, to the point I thought I was getting a stomach bug. It’s still very strong today. My diet hasn’t changed. I have gotten indigestion a couple times but usually after strong coffee or something with a lot of cinnamon. My breasts might be slightly tender but not bad. I know it’s too early to test. Who all has experienced indigestion this early and got a BFP?
