I am so sorry for your mother's loss. I agree with what adgal said.
I would recommend that your mother give herself some time to grieve her loss and allow her body to recover before trying again. This isn't from experience but from following the experiences of others. If the woman doesn't grieve, her grief often becomes wrapped up with the emotions of trying to conceive and makes TTC even more stressful than it already is...
I'm so sorry. I am also in my early 40's and have had the same experience, and I know it's very confusing and very difficult. Unfortunately, even if she had been attended to immediately, there is nothing anyone can do with a first trimester miscarriage. That is why, unless there is very heavy bleeding, most hospitals do not consider it an emergency situation.
If your mom chooses to try again, tell her not to be too afraid. While it is true that there is an increased risk of problems in our 40's, there are lots of us who have had healthy babies and normal pregnancies in our 40's. I had a few losses, then had a healthy beautiful baby boy at almost 41. At 42, we are attempting to get pregnant again. There are so many women like me out there who have had similar experiences. Dr.'s will tell you the stats and odds, and while they should be taken into consideration, they should not deter you if this is what one really wants. All the best to your mom and family, and again, she is lucky to have such a caring daughter. Take good care.
Thank you, for your reply and concern. I am sad to inform that on Nov. 1st my mother went to the hospital and found out she had a miscarriage. She was really sad and upset since she went at midnight to the hospital and was not attended as soon as possible, especially since it took almost to 2 hours to be attended and confirmed of her condition. She was even more upset when they told her nothing could be done. It was until Thursday, Nov. 3rd when she had the appointment to be "cleaned out" by her specific doctor. After that day she has been resting as the doctor told her and my family and I have been trying our best cheer her up and keep the house in order. My mother has started thinking of trying again but is scared and unsure since the doctor told her she should wait and there's a higher risk of certain mutated genes such as down syndrome and others, to develop at her age.
What the report is saying is that she is 7 weeks, 2 days pregnant. This means it has been 7 weeks, 2 days since the first day of her last menstrual period, and that the sac is measuring according to that. It also say's that no fetal heartbeat can be detected.
Typically, at 7 weeks, 2 days, you would see a heartbeat. However, that does not necessarily mean a miscarriage, nor does the spotting mean one. It does mean that a follow up ultrasound is necessary, probably in a week or so. I will be honest, not seeing a heartbeat at that stage is not promising, however, it is possible all is ok. If I were her, I would be hoping for the best, and prepared for the worst. Your a lovely daughter for being so concerned and caring for your mother. I am sorry you are all going through this, and will be thinking about you all. All the best.
