Ok weird ... should i have preggo signs already?

My LMP was april 4th. Me and BF did the BD on the 14th and the 20th. (He was out of town between there). Anyways, I ovulated on the 19th and 20th. I got a cold sunday and still have the sniffles. Anyways, last night I started itching EVERTWHERE!! Nonstop! Drove me up the wall. All better today. My nipples are ultra sensitive and I have montgomery bumps already. My cm is super thick and lotiony but sticky. My thing is AF isn't due until the 4th. Could this be preggo signs? I normally get sore BBs but its normally the whole BB not just the nipple. I also normally get montgomery bumps the day after I start. Any advice is helpful.
