With this and my last pg from about 4 weeks. By the time I was 7 weeks I was so sick I'd lost 6 kilos

With my first pg no symptoms until about 6 weeks then more normal manageable ms.
With my second pg I had no symptoms at all, wouldn't have known I was pg until my belly finally popped out at around 5 months.

Try not to worry just because you don't have symptoms doesn't mean all is not well xx
