I had sex this WHOLE month and I'm not pregnant WHY😢

Don't you hate that feeling when your ttc and you get so excited that your period isn't on the way and it just has to come UNEXPECTEDLY😤 I had sex every week in December and December 30th my ugly period just came and now I'm bleeding so heavy I've been trying for a year and this is what I have to get I was suppose to test in January but I guess not since it wants to show up when to have sex again after this ugly thing ends? Hoping for baby in 2016 gl to the rest of you ladies❤️ my periods usually last 5 days.
