So my period was suppose to come on the 18th and it didn't I'm now 3 days late I took a test this morning and it came out negative. Im not sure if it's just early or if my period cycle changed. I've never been late like this I did have some spotting but that's it. I'm not sure if it's was implantation bleeding or not I guess I can wait until the month is over to see if my period comes if not then I will go to the doctors. I'm just lost on what to do!!..
