im confused am I 5 or 6 months?

I went off the pill completely in March and got my period two weeks later, I took two pregnancy tests to verify I wasn’t pregnant. It’s been two months since then and I still haven’t had my period. In April I knew I wasn’t pregnant. I had sex about two weeks ago and took a pregnacy a few days ago that came out faintly negative. Could I be pregnant all or is my body still adjusting since I went off the pill?
Over the course of three months of not getting my period, I’ve taken three pregnancy tests and they all came out negative. sometimes I feel cramps but nothing at all. I used first morning urine when I took the last test. The last one I took the negative line was very faint and not even a deep color but the control window suggested the test was working
I’ve talked to my friends and they also said since I had lost ten pounds in a short amount of time that my body could be adjusting to the weight loss as well?!
