Funny month or pregnant? Your opinion.?

I am not one of those girls trying to aks the internet if I'm pregnant. I would take a test if it wasn't too soon. I'm just really excited and wanted to get other woman's opinions. I am almost a week late and have been having dull aches in my lower back and tummy. I NEVER have pms, i never cramp, i don't get moody, nothing happens to me before I get my period. Never has. So it's not normal that I have dull aches in my uterus and back. I've also been having head aches everyday for a few days and I've been very forgetful and reeeallllly tired, but not able to sleep! I don't know if those things have anything to do with pregnancy, but it isn't common for me. Do you experience these things before your period? I have missed a couple pills this month, but it's not a big deal because we were planning to TTC soon anyway. But I don't know if maybe me missing some pills is making me feel this way, or if it's because I might be pregnant. I've also had LOTS and lots of discharge (TMI, sorry) and it's been creamy and clear looking. Not stretchy and egg white-like. Usually I don't have much discharge and if I do it's white and textured. So I'd love other woman's thoughts on the subject. I know it's too soon to know for sure, obviously.. but I still like talking about it and getting advice. Thank you.
