Control your fever, if ever you have any. High fever is not good during the first trimester. Hydrate well. Consult your doctor. And yeah don't worry too much. It's really quite easy to get sick while pregnant. You and your baby will be fine :)
Ever since im pregnant, now 25 w, ive been having frequent flu and even covid and nope it wont affect baby. Baby is still growing well and healthy. Dont worry too much!
