Could it be twins????

Morgan

I am 7 weeks today. I have 2 boys 8&10. I have had 2 miscarriages in the last 2 years. With any of the 4 pregnancies I was hardly sick. This one though I am nauseous all day and night. And I throw up 3-4 times a day. I sat down to eat an orange earlier and when I tore it open, there was 2 baby slices on the inside! Could it be a sign? Has any of you had signs like that and ended up pregnant with twins?!!!
