Laura, I completely understand feeling you're going to miscarry again. I think everyone worries about it but it's magnified once you have gone through it. Our minds go back to the last time, analyzing every symptom, comparing nausea, appetite, sleepiness, etc. I know about a week ago, I had no symptoms at all and completely freaked out. Then they came back. Sometimes I feel they are there sometimes I think they're gone. I drive myself crazy wondering if it's all just progesterone symptoms or if I'm still PG.
The doctor promised me that symptoms do come and go from one day to the next. I also google everything and it's very common to feel symptoms one day and the next, feel nothing.
I know you don't want to but if there is a way you can go get a quick blood test,you might feel better. I really hope you can go. I know the anxiety that comes with it all too well, but I think it will do you better to be able to rest assured that all is okay.
I completely understand how scary this is. Its very hard trying to stay calm and not expect the worst. I keep telling myself if I'm going to m/c, there is nothing I can do, I'm doing everything right and it's really out of my hands. Take it easy...and really, go get the beta, you will feel better. Thinking of you.
