Freaking out

So I had our son about 2 months ago. We've been using protection but one time he used the pull out method, stupid I know. However my partner said I'm getting an abortion if I ever got pregnant again. Thats a different fight and I dont even want to be in that position. Anyone that has had a baby, was your first period really really light. Like heavier than spotting but lighter than a period and only lasted 3 days.
