nursegator - No dizziness so far. Just constant, all-day nausea. Smells set me off, and I even get car sick when I drive myself. My mother has taken great delight in reminding me that she was nauseous with me for the full 9 months. Eep!
charr - I'm so sorry to hear about losing one twin. We had two implanted and it was hard enough knowing that one didn't take at all. The heartbeat on your remaining baby sounds great, though, so try to focus on being happy about that!
cristi262 - I still think the wait for the u/s was much worse than the wait for the beta. Probably because I'm one of those "seeing is believing" kind of people! Believe me, I hear you on worrying with the spotting. I completely freaked when I had my bleeding on Sunday - and everything was fine, so all my worry was for nothing. That said, it just means I have first-hand knowledge that my telling you not to worry is not going to make you stop worrying. The best you can do is try to keep busy and not think about it too much.
SueQiwi - Yay! I'm so glad you had a great first u/s - I know how worried you were about it. It's funny, I'm 7 weeks 2 days today, but my doctors office somehow has my due date set for Nov. 10. The online calculator gave me Nov. 11. I'm more of a fan of 11/11 as a propitious day, so that's what I tell people who ask.
nancy1 - My only side effect so far of the lower blood pressure is that my nose will not stop running. I'm usually congested from allergies, and instead now I have a constant flow. Ugh.
