Girls, I went to the doctor yesterday. She said the discharge could be due to sexual intercourse. She reassured me, examined me and said everything is in place and measures about 8–9 weeks. But today I noticed I don't go to the bathroom as often as before and I didn't have any morning sickness, even though I hadn't eaten anything. Should I be worried? I'm very anxious since this is my first and much-wanted pregnancy. Please advise.
