No AF No BFP..

Ok so I'm going to try and make this sound normal lol. My lmp was July 13-18 which is normal for me. Then july30-August 7th I spotted. It wasn't like a period just spots. After that my next cycle was due August 10th but never showed so Glow pushed it to August 27th still nothing and now it's be pushed till September 1st. And doesn't seem like it's coming... This isn't my first pregnancy so I know some symptoms but this whole thing has me so confused. I've been cramping A LOT but mainly on my right said and sometimes on my left. And sometimes it feels like a pulling sensation.. Any advice?
