I knew the date I'd ovulated (we were trying for a third) and about 4 days later I said to DH: "I'm pregnant, I KNOW I am, and I'm pregnant with twins, there's a boy & a girl". DH just rolled his eyes and said "I'm sure you thought DD was twins because you were so sick" (This was true, I was so sick with DD that by the 12 week scan I was convinced these must be more than one!)
I took a test 6 days after ovulation (even though I knew it was too early) and got a faint line! So faint that DH didn't believe it. I bought a digital test the next day and it said I was 1-2 weeks pregnant. I used the other test in the box two days later & it said 2-3 weeks so I knew my hormone levels were rising quickly, so the twins idea did cross my mind again but I just thought "it can't be". Unfortunately, on the day my period was actually due, I started to bleed lightly and I became convinced something must be wrong. It carried on, with stomach cramps, and at 5 weeks, the GP told me to prepare for a miscarriage & sent me for an emergency scan to rule out ectopic pregnancy.
I had a dream, the night before the scan, that I was looking after a baby fox and a baby owl, and I was pushing them around in a double buggy and looking after my 'babies'.
We went off for the scan the next day and the first midwife gave me a bit of lecture about early pregnancy tests & said they 'cause all sorts of problems'. She seemed convinced I'd miscarried & was reluctant even to scan as it was so early. Luckily a nicer midwife arrived abs carried out the scan. She told us straight away that I was still pregnant but then she was quiet for ages and I could see her looking at two black circles on the screen. She then told us that there were two sacs and two yolk sacs but it didn't really sink in until age asked if there are twins in the family (apparently my great-great Grandmother had two sets).
I did say to DH: "I TOLD you it was was twins weeks ago!". I'm now 18 weeks and, touch wood, all the scans have been good and the bleeding stopped. We are not finding out the sex, but I still have my gut feeling about a boy and a girl - so we'll have to wait and see!
