Ok ladies I'm in need of some advice.

I attached below a picture of my last period thru ovulation. Ever since last weekend it seems no matter how much sleep I get I'm still tired. We started TTC end of december. End of Janurary was my first period since going off BC. Next period was due tomorrow but as you can see I had 2 days of bleeding and then the 3rd day was just more spotting. Took a test this morning with very 1st pee and it's negative. I have also been have some stomach pain/cramping for couple days now. Just so confused what is going on with my body.
