Insight what dpo I am

Megan • Megan💄 Ortho asst🦷 fur mom to two GSDs🐶 3 miscarriages 👼🏼 expecting our first baby Aug 2019🤰🏼
We BD 13-15. I had positive OPKs on 14-15 and my temp went up on the 16. I've been consistent with my temp the last few days. Ive also had some cramping going on but nothing major. Also, I've read something on here if you temp stays about the same that's a good sign? Any knowledge is welcomed! Thanks (:
