Confused

Tyiquika • Hi I`m Quetta, Im 23 and have a beautiful baby girl name Jeriyah Eileen who stole my whole heart. Im married to my husband of 2 1/2 years and I`m ttc baby #2

I have a regular period and its heavy but for the last two months (September and October) it lightened up significantly but it was still on time.... the doctor said i wasn't pregnant when I went last month and I have no STDS.... this month its 2 days late and I'm having more discharge then normal.

What's going on?
