can i be pregnant

jessica
I have been having alot of pregnancy symptoms but all my pregnancy tests come back negative but the bleach pregnancy test came back postive if i am pregnant i should i be around 7 weeks. I had a period last month but it wasnt usally very very light . just enough for a panty liner (TMI) i havent had one this month i also but have a increase it white discard. can it be that my hcg levels are low or could it be etopic pregnancy . i read on internet other girls was having this issue and they actually was pregnant please give me your feedback thanks :)
