You and your husband have been married for 4 years you have tried to have a baby with him yet you both always failed,but it doesnt make you give up

You check up to doctor and the doctor told you and your husband to drink some vitamins and medicine to make your body more fertile,after day you end your period,you try again with your husband,Its been weeks after you did it with him

One day,you both are in the sofa while watching tv together, suddenly you feel Nausea and dizziness,you fastly rush to the bathroom to throw up,your husband fastly run to you and rub your back "baby,what happened? Are you sick right now" he tilt his head,he is really worried about you,but in the same time it could possibly you are pregnant
