Tamiflu at 25 weeks

Today I ended up in the ob urgent care from flu symptoms. Ended up I have the flu. High fevers, chills sweating like crazy. My asthma also acted up. So the er doc ended up giving me an iv. Through the iv I received two bags of fluid( event tho I wasn’t dehydrated). They also gave me flexeril for the pains a tamiflu pill and a breathing treatment. Before all the meds my baby boys heartbeat was 145-160. After all the meds his heartbeat went up to 170-75. I’m scared to take the tamiflu do to things I’ve read about it. Has anyone taken tamiflu? If so what was the outcome?
