When is morning sickness too much?

I’m 7 weeks pregnant with my first and since week 4 have been hit with morning sickness. Its everyday and I haven’t kept anything substantial down since week 4. I’ve started fainting, having muscle pains, urinating almost nothing and spewing at least 4-5 times a day and spewing blood. I also haven’t had a bowel movement for a week.

Medications my doctor has given me don’t seem to be working and I don’t see him again till 9 weeks. Home remedies like ginger, dry biscuits ect don’t seem to work either

I’ve never felt so weak and ill in my life and surely if I’m not well then Bub can’t be getting the nutrition he/she needs.

When do I put my hands up and take myself to the ER or make an emergency appointment with a different doctor (mine can’t see me at the moment) or is this just normal morning sickness that I’m going to have to learn to live with?

Anyone who has any advice I will be forever grateful xo
