hpt negative opk possibly positive. Anyone else have similar situation? I'm 39 with 3 beautiful girls and I knew with all of them before I got a positive hpt. I felt like I could be pregnant as I've had a lot of indigestion, nausea, gassy, and strange feeling in my stomach last 2 days I felt as this I can feel the butterflies and the twisting.
