This is the cycle I'm on. I desperately do not want to be pregnant. I had HG in my last (and only) pregnancy which I think started at about 4 weeks. I feel awful, vomited lots last night and it's just nausea today.
My period is usually more like 7 days too so I'm panicking that the four day one wasn't even a period and I'm going to be one of those 'I didn't know I was pregnant' women.
