Think its safe to say I'm preggo

Af wasn't due until the 15th and I think its safe to say she isn't coming....been getting faint lines on cheap walmart ones since sun and these 3 were taken from left to right Mon night,tues night and this morning. Now how to break it to hubby lol he is going to pass out!! Our youngest is 1 and was a preemie. Anyone have any ideas on how to tell him without giving him a heartattack lol I wasn't expecting to find this out the week I turn 41 which my bday is tomorrow!!!!
