Possible pregnancy??

Savanna

I’ve took so many pregnancy tests!! They all say negative. I had 2 periods in December the last one I cramped more that I bled, which was not normal for me. I basically spotted through the whole time. My period usually last 7 days, it only lasted like 5 in a half. I feel like I’m pregnant!! I already have one baby and he is 8 months old! Okay so listen to this!! When my mom was 18, she was pregnant with my sister angel. Well, she took pregnancy test after pregnancy test and they all said negative!! So did blood work and Uran tests!!! The doctors did an ultrasound when she was 7 months pregnant. They told her she was having a girl!! I don’t know what to do:(
