morning after pill (TMI)

hello ladies, just wondering I took the morning after pill... hubby and I got frisky about a week ago. we hardly ever get it on anymore. we just had a baby and have a toddler too. so we appreciate all the sleep we can get. anywho. we got frisky and in the midst of the darkness (our children sleep in the same room as us so he didn't want to wake both kids up) he couldn't find his condoms. we went at it anyway but he pulled out.

I still took the morning after pill just in case, but I've been having cramps since yesterday. my legs hurt and I have been spotting. I'm wearing a daily thin pad I'm not soaking my pads but still... I had never taken plan b. because I was having trouble at first getting pregnant. (lol then first one and six months later boom pregnant again) so is this normal? my gyno isn't available right now.
