Try not to do too much research on the internet about pregnancy complications. When it comes to personal experiences and illnesses the internet tends to provide a worst case scenario. People seek online support and share traumatic experiences when things go wrong. If there were no complications or there were complications but everything turned out OK in the end, the story is less likely to make it to the internet. The nice stories may not be sensational enough to share or become popular. If you start to research medical conditions on the internet, you will come across information and stories that will depress, upset and worry you. You are better off speaking to your doctor or specialist.
Whilst personal experiences have tremendous value, they can become overwhelming. When it comes to pregnancy and parenthood, everyone has an opinion. A little helpful information here and there from friends, family, even strangers, about what to expect can be comforting and useful, but when someone badgers you about what you should or should not be doing or eating, either switch off or ask them to stop. Becoming stressed about the hundreds of ways you could harm your unborn child is not healthy or productive. Try not to let other people's birth stories frighten you. These stories are in no way indicative or what will happen to you, what will be will be, worrying about it is going to help no one.
Ignore the old wives tales about what sex your baby is. You will have people swear they know the sex of your baby, but they will only repeat the story later if they were right. Usually all the strangers who claim to be experts on predicting your baby's sex will not agree with each other. Just go with the ultrasound technician on that one. If all your clever strangers agree with each other, that's quite convincing, but please do not decorate the nursery based on what they say alone.
When you are pregnant, people are drawn to you, you may to start to feel like public property. You are not public property and it is not suddenly acceptable for someone to stroke your belly just because there is a baby inside it. Feel free to speak up or withdraw from the tummy stroking.
If you are making a birth plan, do not get too attached to the idea that what you are writing will actually be possible. There are few experiences less predictable than giving birth. Nobody knows how it will go, you cannot possibly predict what will happen to you in labor or how you will feel. By all means make a plan but try to accept that it is not set in stone. Try not to worry too much about the details beyond expressing your wishes and reassuring yourself that you are being heard. Active labor is unfortunately not a situation where you will have a lot of control. Try to come to terms with the possibility that the unexpected could happen and find a doctor or midwife who you trust and has your best interests at heart.
