5 weeks pregnant and no real symptoms yet

So I am 5 weeks and 1 day with my 3rd pregnancy. I had an ectopic back in January. My boobs were fairly sore with the ectopic and my 1st child. If I push my boobs a certain way they might hurt a little and my nipples are tender only if I touch them. I have no nausea or vomiting. I am, however, very bloated. Occasionally, I feel a dull pulsating pinch on my lower left side that comes and goes. It jdoesnt really hurt, more annoying and uncomfortable. It worries me that I'm not feeling more. I'm sure it's coming and will change my mind later, but it still makes me a bit nervous. I don't get my ultrasound until the 26th so there's that... Another 2 week wait and it's killing me. Anyways, do any of you have similar or lack of symptoms like I do?? Is the pulsating pinch common?
