Hey... I think I just had implantation bleeding but I'm not too sure.. on the 13th I noticed a bit of blood so as per norm I ran for my tampon and hours later when changing it I noticed there wasn't much blood and I didn't panick cause oh well it was the first day of the cycle. When I woke up the following day to check there was nothing there and then later on in the day I was 'bleeding' again. This went on until the 15th, where id see blood and then no blood. Its now the 19th and not a drop of blood so I'm not sure if this is an indication that there might be a little someone growing in me or not... must I get tested or wait a while?

At this point most likely you will need to wait till next month and see if you have that period or not before you test. You may try a test in two weeks
