No, sweetheart. Your c-section wouldn't have affected a different pregnancy.
I am sorry for your loss. :(
Early miscarriage happens in a surprising number of pregnancies; the statistics suggest the number might be as big as from 1 in 3 to 1 in 5 pregnancies. It happens because a whole lot has to go right when an egg meets a sperm, to give the resulting embryo everything it needs all the way to becoming a healthy baby. Sometimes, something is missing when the egg is fertilized by the sperm. The embryo will start to grow, but when it reaches the stage where that thing is needed, it isn't there, and the pregnancy fails.
All I can add is that women are said to be particularly fertile after a miscarriage, so cross your fingers for next month and try again. Again, I'm sorry to hear of your loss.
Ah, sweetie. I'm very sorry to hear this! Please know that miscarriages are usually nothing anything a woman did nor do they mean she can't have kids. One in four pregnancies ends in miscarriage. That's really what the odds are. The vast majority of those women go on to have healthy pregnancies!! You'll have your baby! previously, we often didn't know we were really pregnant at 4 weeks but with the onslaught of home pregnancy tests we now know. in past generations, women would get a heavier than usual period they would think and never know they were pregnant. But don't despair. You should have no problems getting pregnant again and carrying the baby. If you do, then there are numerous things they do to help with fertility. The statistic is that 95% of women that want to give birth, do so. So, please do not worry. Again, I'm very sorry for your loss though. I know how disappointing that is. hugs
