So I got the flu for the first time 5 days ago, started out nauseous and puked and progressively got worse ending up with a fever and going to the er. I'm a healthy 25 yr old and never get sick nor was I around anyone that was. But my dh and I have been ttc for 7 months now with no luck and I'm 3 days late. Just wondering if anyone has found out they were pregnant after the flu? I took tests at the dr and they were bfns. But I know pregnancy can weaken the immune system? I'm recovering from the flu symptoms but still very nauseous.
