Well, here's the thing: I had a very irregular cycle with my first two kids. I got pregnant with hormones for the first two, and the third one happened spontaneously. In between, my cycle was sometimes irregular, but also regular now and then. But since September 1st, I haven't had a period at all. I've had unprotected sex twice. I had some vague symptoms, and even though I thought it was almost impossible, I decided to test anyway. At first, I thought I saw a faint line on the Action test, so the next day I did a Kruidvat test too. The last time I had unprotected sex was December 16th.
