I had the same thing happen to me. I'm 6 wks today. Once I discovered I was feverish I called the OB and they said keep taking Tylenol until the fever breaks and that's exactly what I did. Mine didn't get over 101.5F. Also I read that taking folic acid can help with the NTDs. Were you taking prenatal vitamins? Luckily I was/am taking extra folic acid on top of the prenatals. So hopefully everything will be OK. I've read the studies too but for now all I can do is pray that the tube closed up. Good luck.
When I become pregnant I get flu like symptoms. I spike a fever and get congested, feel like my head is clogged. When it happened the second time I realized it was my body's way of letting me know that I am pregnant.
Follow your doctor's advice and monitor your fever closely. I know that you can not take a lot of drugs during this time but your doctor will let you know what you can or cannot take during this time.
Please don't stress yourself about this too much. I am sure your baby is fine. I will keep you and your unborn in my prayers. Oh, and please keep yourself hydrated.
I had the flu when I was around 4 or 5 weeks pregnant but I knew that I couldnt let my temp get up, so anytime it got to 37.5 (I'm from Aus so dont know what the equivelant for you would be - maybe 101.5?) I would take some Panadol to keep it down.
I dont know how high it has to get to cause problems, but I think it would have to be high for a while. How high did yours get and did you take anything for it? Also aspeak to your OB and see what they say.
How high was your fever?
I had the flu on the day I was inseminated, and again when I was 6 weeks pregnant! Both times I had a fever of about 101.5 F, but from my understanding, that's not really high enough to cause a problem. I think a fever of 103 and up is where there could be issues.
If you're worried about the neural tube thing, talk to your doctor about it and see what they say.
