Pregnant?

Okay so around early august I took a pregnancy test as I had alot of the symptoms and my period was a week late but it was negative, I decided to wait a bit longer as it might of been too early to tell. However I got my period 2 weeks later and jusr shook everything off as me and my boyfriend are bot TTC. I still noticed I was having symptoms but I was getting my period sometimes light and short but mostly heavy. But I remebered my sisters friend had periods all the way through her pregnancy and I searched it on the Internet and other women had done too, this morning I noticed a baby like bump. Any one had periods during pregnancy or any ideas or thoughs?
