Thanks so much very helpful
Don't worry it's very normal. I had the same in week 4 when I first realised I was pregnant. I was bloated for quite a while and even had difficulty with constipation. The uterus is stretching to make space for your baby so that's why you will feel mens like pain in you lower abdomen. Avoid sitting in hot tubs but you can put a warm pillow or a bottle with warm water on your abdomen to relax the cramping.
Hey im 9 weeks and when i was six weeks i was in very alote of pain like period pains back pains and alote of bloating, ypu will bloat alote and atm your baby is the size of a berry not even that its your insides stetching out and thats what makes you bloat and look bigger then actually how long you are, if ut gets worse go to see your doctor :)
