Will these temperatures hurt my pregnancy?

[annabelfr]

I’m currently 4 weeks and 2 days pregnant (IVF, FET), and I’m really worried that I might be running a low-grade fever and that it could harm the baby, especially this early on.

I don’t fully trust my thermometers because they keep giving different readings, but here are my recent readings, all within a 10 minute interval:
Ear thermometer:
• 37.7°C (99.9°F)
• 38.1°C (100.6°F)
• 37.6°C (99.7°F)
• 37.9°C (100.2°F)
Armpit thermometer:
• 37.1°C (98.8°F)

I’m not shivery or dizzy, but I have a sore throat and a bit fatigued and a little warm. Haven’t taken paracetamol yet.

I’m terrified of neural tube defects or harming the embryo at this critical stage.
Have any of you had temps like this this early on and gone on to have healthy pregnancies?
Should I take paracetamol now, or wait to see if it holds steady?

Any advice or reassurance would really help. Thank you.

Most important thing is to deal with the temperature so the first thing you should do is take Paracetamol to treat it. Take lots of fluids, keep yourself cool in light layers and take paracetamol as prescribed 4-6 hourly max 4 times in 24 hours. Anything else is out of your control, could see GP if you want to rule out any infection. Is there a reason you haven't taken Paracetamol?

@Lavenderandlemonsi haven’t because I guess I didn’t know if I should.
so let’s say I’ve had a temp for the full of today (I’ve only just measured it) - has this damaged my baby and is there anything I can do?

You have a low grade fever but this won’t hurt the baby. Treat your fever with paracetamol and try not to worry. I had covid twice in pregnancy and nothing bad happened.

A sustained fever for 24 hours of 39C or more is most risky. Considering yours are quite low grade and only actually hit fever territory of 38C once, then Id say the risk is low. But I can't answer that with certainty, just seems less risky when you look at the stats. Try not to panic just treat the fever from now on and feel better soon.

Thank you @Lavenderandlemons@DamnitCarol!! I have now taken paracetamol and it’s around 37.3-37.7 on an ear thermometer

No a low grade fever won't hurt the baby. There are some pain/fever relief things you can take but I can't remember which ones.

I was incredibly hot (I could sit still and think “heat” and make beads of sweat run down my front) on the IVF drugs around the 4-5 week mark like you and asked my consultant the same neural tube defect question. He was so so unbothered.
