Nauseous

For the past 2 days I have been nauseas after I eat the littlest bit of anything. We haven’t been trying to get pregnant... but we aren’t preventing it either other than the occasional PO. My CM has been heavy and creamy for 2 days as well and I have had a continual moderate to excruciating headache. Last week I bled for 1 days very heavy and the next day light and it ended. I use glow just to keep track of everything.... and I am due to OVU on the 1st.....
