Help ?

My lmp was Feb 23 , my period is very regular 5-6 days , first 2-3 severe cramps , & heavy bleeding until the last day.

About a week ago I had a light pinkish redish color when I wiped for 2-3 days ,it didn't show up anywhere else (I wore a pantyliner) & I had no cramps at all , but I have a few other symptoms that normally come with my period but apparently happen with pregnancy to ? I've been pretty bloated & gained a few pounds from eating so much , I've had slight headaches on & off & mood swings (really irritable) my stomach & abdominal area are kinda hard to the touch (only way I could think to describe it) but idk what to think , I took a clear blue test & it was negative so I'm gonna take another in a few weeks ?? Any advice or people that've dealt with the same thing ? This is the first time I've ever thought I was pregnant so help ?
