I can definitely relate- my first pregnancy I tripped along to the 12 week scan, to be told the sac was no more than 6 weeks; rescanned a week later, no growth, MMC diagnosed, surgery next day. I was shell-shocked.
14 months later conceived again, natural miscarriage at 6 weeks.
Next cycle, conceived DS- was very anxious for the whole pregnancy, but he is perfect and now 2.5 ❤️
When he was 1, started trying again- fell pregnant in January this year, but at 12 week scan (after early good scan seeing a heartbeat) we were told baby had died at 13 weeks, another MMC. I opted for surgery again as the least traumatic resolution. Genetic testing was performed and the baby had a completely random chromosomal abnormality that was unlikely to recur.
I'm now 16 weeks pregnant. Yes I am anxious, as with DS I find it hard to believe that pregnancy = baby, but am trying to enjoy every day of being pregnant and have faith.
Having one, or many, miscarriages doesn't mean you won't carry to term in the future. Try to stay positive and hope it will work out.
