Food poisoning

Hi Mummies! Should i be worried? I had food poisoning last week and have diarrhoea for like 3 days non stop, each day went to the toilet 6-8 times, had fever as well. Even went to the A&E for drip as i was dehydrated but the hospital wasnt equip for a ultrascan in the a&e. My next gyne appoint is on the 27th Apr. My symptoms almost all gone after what happened last week. I had my first scan on 27th mar, ard 7 weeks 4 days. Today i should be 9 week 5 days. Should i go to see my gyne sooner? Super worried as its my first pregnancy and was told its super hard that i could be pregnant with my current weight(im super overweight) #advicepls #pleasehelp #firsttimemom
