Trying for a bundle of joy! - Please help!?

My husband and I are TTC our first child! I had my period on the 4th of April lasting about 5 days. I ovulated on the 17th. We had on the 13th, and the 16/17th. I ovulated on the 17th of April. Sunday (17th) I had some spotting on my underware, i've been cramping every since. My are very tender, but not sore. I feel more bloated than ever! Since the 18th I've had egg-white discharge which is now clear and watery. Every morning I get up I feel slightly nausea, and before bed but I have never gotten sick. I've taken a hpt which of course was a BFN. I was wondering if anyone has had similiar symptoms and got their BFP??
