What’s going on?!?!

Currently 8 dpo. I’ve been tracking with OPKs and got a positive on 2/25, still high on 2/26 - we bd’d and I’ve been having some symptoms like heartburn, light cramping early dpo, bloating, heavy boobs, but of course can’t tell if they’re early pg or just pms symptoms (TTC #1). I’ve been having small amounts of ewcm for nearly 2 weeks now! This has NEVER happened to me before, I always stop getting ewcm a day or two after ovulation. It’s still there but getting a little sticky now. Took another opk this morning and it was high, not 100% positive but like 1 shade lighter than a positive. Has anyone else had this happen and still got a bfp? Did I ovulate later than I thought, even with the positive OPKs earlier? Can you have clear cm post-conception/implantation? Thanks for any help, I’m driving myself crazy!!!!!!
