I'm on the pill. Have been since Christmas when I had my son.

I had a week of taking it later than usual by a few hours and completely missed it on Sunday. That day we had unprotected sex.

I've been spotting for a few days and my sense of smell is really strong like when I was pregnant before.

I took a test a few days ago and the line was horizontal not portrait but there was a faint line

I tested again last night and there was nothing.

But I have quite a lot of the same symptoms I had with my son.

What do I do?
