Constant flu since tri 2

Have been down with flu/colds for the past 2 months or so. Each time, recovery takes around 2-3 weeks, and by the time I’m almost better, I get hit with another bout of sickness. So had like 4 bouts of flu over 8-10 weeks already. And with each recovery taking so long, I’m almost perpetually down with something. Feeling super congested and coughing. Almost every time there is a mild fever. And 100% of the time loss of smell. And I had a flu jab. Nope meds and jab didn’t bring me the relief I imagined. I feel so defeated because of ongoing cycle of flus. Anyone also experienced persistent sickness? Did it affect the baby?
