Early in my pregnancy I bled a few times. At least two of those times was due to hemmorhoids but each time I saw the blood it scared me to death especially since I've had 2 previous miscarriages.
I saw the doctor each time I had bleeding and they also checked the baby and I could hear the heartbeat or see the baby if they did an ultrasound and it was a HUGE relief just to know that the baby is still okay.
I didn't get puking sick with my pregnancy (I'm 31 weeks now) but I did get the diarrhea side of the sickness and I was told similiar to what they told you that it is most likely irritating that area and so every time you have a BM it just reopens that hemmorhoid. Does that make sense?
I bought some Preparation H stuff-the cooling gel, it helped with the pain that I was feeling in the rectal area, the wipes and you can even take a warm bath with epsom salt, it helps.
But I think if your doctor can see you sooner, it may do you some good. Give you some piece of mind at least.
