Needing some advice please!

Hello ladies, I had a miscarriage back in July of last year and ever since then, my heart has been breaking every month. When I was pregnant in July, I knew it right away and tested the day after my missed period and had a positive. 5 days later, I had a miscarriage. It was a rollercoaster of emotions in such a short time. Well, this month I have been feeling different. I am currently 3 days late but have taken some hpt and all came back negative, I think I tested too early twice but the third was the day of my missed period. This morning I felt very nauseous but didn't throw up. I have had minor cramping over the past couple days, where as my period is so painful I can't move. My boobs are faintly sore but not my usual pms symptoms. I'm just feeling really lost and could use some advice or help! Please and thank you! And baby dust to you all!!!
