So I started a new job on Monday. Two days a week. Mon and wed. Trouble is I'm 7 weeks pregnant. I wasn't pregnant when I was offered the job 2 months ago. Things took so long to process due to the nature of the job and the checks that had to be made. I've been so looking forward to starting then I found out I was pregnant 2 weeks before I started.
I was going to wait until after the 12 weeks scan to say anything as if something goes wrong then I wouldn't have to explain it to people I don't know well etc. And they'd maybe be less inclined to let me go if I can do a good job in that time. Though my probation is 6 months so they will have to know before then, so could find an excuse to just get rid of me 
Trouble is i've been hit with horrendous morning sickness that is getting worse with each day. I'm even waking in the night feeling sick and spent all day today throwing up.
I just don't know what to do! Do I have to just tell work why I'm running to the loo to throw up on my second day and that I won't be around in 8 months time (all being well), or do I try my best to cover it up and power through until the 12 week scan. It's only 2 days a week after all.
Advice welcome and appreciated.
