Irregular and confused ❓❓❓

Britany

I use to have the ideal cycle and knew my body so well. Since taking myself off the pill in 2014 to TTC #2 it has been a rollercoaster as far as my cycle. It has a mind of its own. I took myself off the pill in may 2014 and my body didn’t react well. I bled until October when I finally went to the doctor. He put me on a few different pills as my body wasn’t responding well to a few pills. I finally was able to conceive and gave birth October 2016. I breastfed and my cycle returned at 14 months postpartum ( no complaints there). In November 2017 I went back to my OB and had the Marina IUD put in and in may I was still having irregular cycles (should have stopped by the third month of having the IUD). And the IUD was inserted incorrectly! I had to have it out it wasn’t even preventing pregnancy at all. The Doctor recommended me not be on anything for a few months as my system looked very angry on ultrasound. My “period “ was 6/6-6/10 but had light bleeding through the 20th. I did have sex on some of my predicted fertile days and I have not bled since the 20th. I took a pregnancy test a few days ago and it was negative. I don’t know what to expect as this is the longest stretch of having no bleeding. It is nice not to worry Day in and day out but with it stopped like that idk if I could be pregnant and tested too early or is my cycle just getting back to normal??? What are your thoughts??? Sorry so long!!
