Worried 😩

Hello all, I am trying to conceive after I suffered a miscarriage the day after my birthday in 2015. My menstrual was 01/30/17-02/03/17... my hubby & I BD 02/10/17, 02/11/17, 02/12/17, 02/13/17 (We had a lot of spare alone time, LOL)... I had egg white cm on 2/12/17, and now when I randomly wipe I see a little more here & there. My boobs have slight sharp pains & I have mild cramping on my left side & randomly in my back on the left side. Sometimes it feels like pressure/dull cramps in my pelvic area. I'm beginning to think something is wrong. I never experienced this with my first pregnancy. Anyone know what this could be?Â
