Birth control mess up

Beth

So long story. On the nuva ring for birth control i put my ring in march 25th I took the old ring out and inserted a new one right after. (Trying to not have my period) but I ended up having it the fallowing week anyway. I forgot about my nuva ring and left it in for 38 days. Took it out Tuesday may 1st. Took a pregnancy test was negative. Started lightly bleeding may 10th and may 11th then no blood (which I usually bleed for 5-6 days. I've been waiting for a actuall period to but a new nuva ring in. But it look like I may have had I'm implantation bleeding as I did with my first born on may 19th. I'm thing and hoping I might be pregnant trying to think positive but I could be wrong. I'm not sure when I should be starting my next period. Any opinions
