Colitis flare-up again!!

[MrsNutkin]

Have not had a flare-up for about 18mths, am 15wks pregnant with my 2nd and have started having symptons of a flare-up, painful cramps, vomiting, headaches and sore joints. Gp keeps putting it down to pregnancy symptons but am so sure it isn't and don't know what to do. Haven't been able to go to work the last 3 weeks and just getting more and more frustrated!
I haven't had a flare-up since soon after having my ds and felt great(which was just over 18mths ago)and was just wondering if anyone has felt fine with no uc symptons after a pregnancy then had flare-ups during subsequent pregnancies?and is this normal?
Am also worried about taking time off work as feel like I'm messing them about. Sorry just ranting now as so fed-up.

This might sound a strange question, but do you smoke when not pregnant?

There is an association of reduced symptoms of UC when exposed to nicotine this link

So if you normally smoke, but give up during pregnancy, then it could follow that the UC flares up. I have heard of tobacco enemas being given as direct therapy to the colon, but not sure if it is advisable during pregnancy (or even something that one fancies doing ).

No Ive never smoked, so no idea what it is. Had heard that could be a hormonal thing but the doctor just dismissed that!
