i feel really tight cheated today. It's not the first time. I am pretty sure it's due to being anxious/stressed. I feel lightheaded and have the flashing lights in my eyes. I thought that was normal for pregnancy. Am 22 +6. Bloods are normal and so is my blood pressure. Is this normal? I would call my community midwife but I can never get hold of her, I'll leave a message and she never gets back to me.
