I'm 11 weeks and 1 one day pregnant with my first baby. I was between 100 and 105lbs before I got pregnant at 5'2". I started showing at around 6 or 7 weeks. I've been in maternity clothes since 9 and 10 weeks. Our first Ultrasound is tomorrow on the 7th. We know for a fact I'm not farther along, or that we miscalculated. My husband is in the Army and visited me on the time of ovulation. This baby was planned. My family does have a history of twins BUT we are really young (Very early twenties) for that to be a BIG concern. So, my question is, is it normal to be in maternity clothes so early? On that note, the line from my belly button to my nether region has been visible since 8 weeks. Are twins something to be expected from this? Can my fast growth tell the gender(s) at all? What do you think.

Some additional info:

I have been showing clear symptoms of pregnancy since four weeks.

Morning sickness has been mild, usually nausea with occasional vomiting

Breasts were fine until 9 weeks,now sore with deep blue veins around the areola and slightly purple nipples (usually pink)

Shortness of breath nearly always

Certain smells and sounds make me sick to my stomach

CONSTANT fatigue

swollen feet and hands

RLP since 6 weeks

Occasional tingly feeling where the baby is since 9 weeks
