7 weeks pregnant and feel horrendous

Hi there,

So I’m 7 weeks pregnant tomorrow or there abouts, I want to be so excited but dubious after our ectopic pregnancy last October. We’ve had a scan and seen the heartbeat but still we both ain’t getting too excited until our 12 week scan. That aside I feel so so ill, so exhausted but so sick, not actually been sick but nausea all day long. All I want to do is lay down, I’m dizzy, even when sitting down and walking around. My head is fussy and I have a horrible taste in my mouth I can’t shift. I felt that bad I even went to the Doctors on Friday but felt so silly when he just said it is pregnancy and it’s all due to the hormone changes and amount of extra blood flowing around my body. Has anyone else felt or feeling this bad. Iv been pregnant three times prior- twice to two boys and lastly to angel baby. I never felt this bad- flu like ill. I’m drinking, eating small but often, sleeping, taking vitamins but nothing is shifting the feeling of zombie.
