Missed my period!!!

Ugh help! So I've been trying to get pregnant. I had my daughter only six months ago , yes I know it's sudden but I'm ready. Anyways my boyfriend has came inside of my well over 10 times and I haven't had my period in about 2 months now. There was a day about a month ago that I bled for a day straight and then just didn't believe anymore and I took a test a week ago and it was negative? Any chances I could still be pregnant and it takes more time to show up??
