Multiples or One baby??

Destinie • Redhead. Mom of two. Newly inlove. Christian.

So I am currently 6 weeks and 6 days pregnant. I'm gaining weight like crazy, my clothes are already too tight and I eat like every two hours (if I don't, my stomach growls super loud as if I hadn't eaten in weeks, despite eating two hours earlier) My boobs hurt like crazy, more the left than the right. I'm almost constantly nauseous and fatigued. My sense of smell is so sensitive that the slightest disgusting or unpleasant smell sends me barfing in the bathroom. This is my 3rd pregnancy (1st one was a miscarriage 7 years ago and 2nd one was successful almost 3 years ago.) I know that every pregnancy is different. I completely understand that. I'm just wondering if maybe I could be carrying twins (or more) My first appointment isn't until the 23rd of the month. Any mom's of twins (or more) have anything similar? What were y'all's pregnancy like? I could use all the advice I can get. I really am confused about what's going on in there. Thanks in advance.
