high opk for days? could I be pregnant?

Leigh

I only bled for one day this month (usually I bleed three) but it was a normal flow on Oct. 8th. Now I have been taking Ovulation tests for 7days and all are high but no peak (I usually get peak after day two) but my boobs are sore off and on and I am having cramps. my CM is super watery. I took a pregnancy test but it was negative. So confused. has This happened to anyone else and what was the outcome?
