Help, negative test but vomiting/late period

[ttcchapter2]

So period was due on the 18th (I think) my cycle is usually 28-30 days, did a test on Monday but it wasn't FMU and was negative. Just a clear blue rapid result one.

Its now Wednesday and I've been feeling awful and nauseous since yesterday and today have actually thrown up.

Called GP surgery and she said to test again, doesnt matter what time of day I test but should I wait till the morning or what?

We're not trying but we're not, not trying??

Do another test with fmu. And don’t use clearblue.

When I was pregnant with my 3rd , I was getting negative tests for about a week after my period was due.
I always thought morning sickness didn't start till about 6 or 7 weeks of pregnancy. It could be that you have a bug ( pregnant or not)

@Mairzydotes definitely feels like a bug but so puzzled about the period. Will try fmu and see how I do.

Has anyone else had really bug like symptoms and tested positive?
