Darkening Ovulation Test

Okay so i’m very confused! I recently posted about my boyfriend telling me i felt *different* during sex and he didn’t notice it until 5 days before my AF. I am now 2 days from my AF and I’ve been taking LH tests for the fuck of it. I tested during my fertile week which was the Feb 23- March 02. On the 27th I had gotten an almost match on my ovulation test and then on the 28th the 2nd line was almost completely gone. So I assumed that I ovulated between the 26th to the 27th. I tested again on Sunday and noticed that the line had began to get darker. So, I tested again today, 2 days before AF and the line is getting even darker. Is there any reason why the tests are saying i’m getting closer to ovulating if i’m right about to have my period? could this mean i’m pregnant? I’m confused. I have been feeling super nauseous and my boobs are super sore, unlike anything before and i’m bloated and etc. I’ve been passing these off as AF symptoms but could it be more?
