Pregnancy at 16 weeks

[user1490291922]

Hi everyone! I'm 16 weeks today and been trying to keep myself really healthy.
I've luckily not had any pregnancy symptoms at all and the only thing I've felt is super tired! Randomly today I have been violently sick twice for no reason as I am not unwell. Why would I be out of nowhere having pregnancy symptoms? I'm a bit of a worry guts so just want to check that nothing could be wrong by being sick! Thank you :)

I was like this - only been sick 4 times throughout this pregnancy and no reason for any of them! Don't worry unless you can't keep anything down then ring 111 xxx

I'm 34 weeks by the way xx
