Sad to say - but yes. I don't remember it with my first pregnancy, but I'm 17 weeks and still very gassy! Just another wonderful pregnancy symptom =)
I am soooooo bloated with this pregnancy, not so much gas but bloatedness and my OB/GYN said that is very normal. Some women have it some not, usually it goes away by the end of the first trimester. BTW my bloatedness is made worse by milk products so I try to minimise them as much as I can.
I had lots of gas really early in my last pregnancy. It feels uncomfortable. Eating smaller meals helps (I found it was worse after a big dinner). Peppermint tea is good for increasing digestion and helps a lot with gas. try drinking it after every meal. If drinking peppermint tea doesnt help try getting on the floor on your knees hands flat on the floor and put your head down so your bum is in the air it can help release it. You feel ridiculous but it helps.
Some women will have more gas in early pregnancy. The nausea is 100% normal. I had that for 8 months straight. And am dealing with it still 9 months after delivery.
