TMI but... TTC for 4 years and this cycle is odd

New to Glow. Was using other apps before. I'm familiar with CP, CM, my cycle etc. 
So anyways...
My period was about two weeks ago. Very heavy to the point of needing to change the sheets. And we were away on vacation.... Embarrassing! 😳 The week after my period I felt like the flu was coming on. Nausea, headaches & almost vertigo. It passed after a few days and signs of ovulation began this week. Light cramping, CM, CP etc. 
We BD a few days ago and then last night. Fertile window was 5 days ago to yesterday. I took an ovulation test yesterday which was negative. BUT I did a first timer type of thing and kinda dropped it in the toilet.... Lol. This morning it says positive. 
Here's where my questioning is, I had fertile CM yesterday & the day before. Today I'm fairly dry but at the same time wet to the point it's on my panties. That never happens for me. 
Also, both BD (this is the big TMI...) I was uncomfortable. Like, during foreplay, I was sore and it almost hurt to have him touch. I'm certain there's no infection going on. Today I don't feel as sore. Just somewhat sensitive. Have any of you ever experienced this? Could it be just exceptionally good timing for BD? 
We're going to BD again today to hopefully seal the deal. And I'll start HPT in 10 days. If I can make it that long. TWW always drives me nuts!
Thanks in advance!
