Confused!

Breanne

So I had a period for 2 weeks (which is typical for me), and now I'm going on 3 weeks with no period. For my body I am late about a week now, and I have taken 2 pregnancy tests. Both of them were negative. The first test I took I forgot to take in the morning, so I took a second one this morning with my first urine. I have had off an on bleeding gums, and extra discharge. I did also just have a still born. I was 23 weeks gestation, and gave birth to her on June 28th. I bled off and on for close to a month, then this last period was my first one since. I'm not sure if my body is still going through some changes or if it's just to early to tell if I'm pregnant. Please help! Thanks.
