Help!!!

Brittany

3 weeks ago I had my period. 2 weeks ago my husband and I had sex. Yesterday I woke up and when I used the bathroom I noticed medium red blood. As the day went on, it got lighter and today it was brown and I’m experiencing some pressure. Clearly it isn’t time for my period. It’s not for another 2 weeks. We’ve had 2 miscarriages however I can’t help but get excited. Am I experiencing implantation or is there something wrong?
