Flu and spotting

Erin • 26 Catholic mother and wife. TTC for #2 💑💍👪❤💞
So Monday morning i got the stomach flu, i was pukey and achy and could barely keep anything down. The night before dh and i dtd as we were in our window for ttc well Wednesday i had a little spotting not much and Thursday i had a larger amount and the rest of the week it was either no spotting or extremely light today however...i had a very bright red spot when i wiped. Should i be concerned? Tia
