Sounds to me that you received some very good news. As for the hematoma that the technician didn't see might be because it corrected itself. Also, you most likely are feeling round ligament pain and most likely feel that off and on through and up to your third trimester, sorry. Also, as for labor or impending miscarriage you will feel a more "regular" pain or contractions and t here will be blood too. I am almost 27 weeks and still feeling, on and off, like I am going to start my period (that kind of feeling).
Since you have m/c before it is understandable that you will notice every thing as impending doom, this has to be scarey.
I also agree with sarge1 and kellym that if it worries you enough (or even a little bit) call your doctor as he/she will be able to reassure you better than anybody.
I, too, won't tell you not to worry as it is normal for a mother (or mother to be) to worry.
Good luck to you and congratulations on your pregnancy.
I had a large hematoma that made me bleed through the first trimester but did not cause any cramping. By now it resolved itself. I did start having round ligament pain around 12+ weeks.
I am so glad your baby is doing so well. We had our nt scan yesterday and baby had the nose bone and the fold was at 1.1 which was such a relief!
Try to enjoy all the good news and your growing belly.
I had round ligament pain starting early on-well before my second trimester even started. I know the feeling about not wanting to call the doctor for every little thing, I was the same. But then I thought, what if I don't call, and something is wrong that could have been fixed-how will I feel then? I say call if it will ease your mind.
Well, Congrats and it sounds to me like they saw all of the necessary things to make you feel a little better, right? Plus, a good strong heartbeat has to count for something. You WON'T stop worrying, so I'm not going to tell you to try. Just keep an eye on the cramping and if it continues, call your dr. and make an appt. to come in. Even if only for piece of mind. Plus, you are going to get a little cramping, I felt like I was going to get my period all the time, hee, hee. As long as you have no blood!
P.S. baby's h/b is and has been fantastic - why can't I stop worrying - I keep repeating to myself over and over all the positive things - excellent h/b - excellent n/t number - they saw the nasal bone which is fabulous - baby was very active - and measured perfectly why can't I stop worrying and to boot they said the placenta was on the anterior wall which dosen't make a difference to baby but means it's harder to find the h/b and means it will take longer for me to feel baby's kicks due to the placenta being in the way arghhhhh!!!! I need some reassurance!
