Could this be Implantation?!😍🥹🙏🏻

So this is my first month tracking and actually trying hard. For 4 years my husband and I have been trying but not “planned trying.” I lost my left tube in 2014 ectopic, and in 2020 I had an ectopic in my right tube where it meets my uterus. They did “save” the tube however. No due test done.

Short story long I’ve been cramping since ovulation. That’s kind of normal. It happens for a day or so, but it is happened this time every day since then, and it has moved lower and gotten less, more light slightly pressure or pulling feeling. My bbt dropped .5 degrees and I’m 5DPO. I feel like it’s a good sign but would your temp drop like this normally? Again first time tracking these things. I just started like day after ovulation. Thanks!🙏🏻
