Sugary, another way to think of it is to think of the day you did the deed that got you pregnant. Then count 2 weeks back from that day. That 2 weeks back date is technically the first day of your pregnancy. So, if you got pregnant from sex on, say, August 15, the "first day" of your pregnancy (according to the way the doctors count) would be August 1. So by August 29, you would be 4 weeks. Weird, I know, but it's based on the silly idea that we all have 28 day cycles. If I went by the day of my lmp, I would be 4 months along! I know, though, that I didn't ovulate until day 55, so I am actually just shy of 8 weeks.
I'm still having some mild cramping- for whatever reason mine seems to be worse at night when I'm lying in bed. I've also noticed that putting very light pressure with my hands (really just resting my hands on my belly) relieves the pain. I think the cramping is very normal- there's a lot going on in there! I find it a little reassuring to be able to feel something going on. I think it is nothing to worry about unless it turns into severe cramps, or cramps with a really bad backache.
I'm taking progesterone, 100mg 2 times per day. My best friend was taking 100mg 4 times per day. It made her feel AWFUL. She said starting about 1 hour after she took the pills she was like a zombie. I haven't noticed any problems at all from the progesterone, so it just depends on the person.
I also think it's normal to be very tired. I have noticed that some of my sleepiness has tapered off, but I think I've just gotten used to the idea of a nap each day and getting 9 hours of sleep each night. It could be the progesterone, or it could just be natural pregnant tiredness. Either way, both very normal.
My first appointment, I actually came in because I had had some spotting, so they did an u/s to make sure everything was ok (it was more than ok- twins!!). Some ladies are lucky enough to get an u/s first visit, other not. I guess it just depends on your doctor. They will probably do the following:
take a urine sample at the start of the visit
take your blood pressure
do a pelvic exam/pap smear
and take blood at the end of the visit.
Your doctor may also talk to you about nutrition, and give you the opportunity to ask any questions you might have.
If you aren't already, you should think about taking a pre-natal vitamin with 800+ micrograms of folic acid every day.
If I gave a ton of info you already knew, I'm sorry! I realize I've written a book! I hope this is helpful. Good luck and congratulations!!
