Weird Period

Okay so I just need to share because this is freaking me out... I've always had periods that were regular and lasted 4 days. This month after only TTC for a very short time, my period decides to go all weird. I started very lightly spotting five days before it was supposed to come and that lasted for four days. There was only one day I really seemed to have a period and now back to spotting again. Really upsetting! So this is day 8 and I really just want it over with. I have a doctors appointment tomorrow so I hope nothing is wrong! Does this sound normal??
