I can't bare the pain..

I've had cramp like pain around my stomach and lower area since last night I went to bed and it didn't go away until I fell asleep but this morning it's more intense so I called my doctor and they said "oh you're the one who complained about the same thing last month" and they said this is what pregnancy is all about and I should take Tylenol but I explained I can't walk or go up/down stairs and they said it's normal. Now my back is beginning to hurt and it doesn't go away
