Not sure what's going on!!! 4 days until period due!!

AAAhhh! I'm going crazy!!!

My lmp was Feb 14th, and I have a 34-36 day cycle. So I should be starting again on the 19th of March. I'm going crazy! Starting just 4 DAYS AFTER OVULATION I was nauseous, and had really sore (take your breath away) boobies! I mean they start to hurt and all I can do is hold them against me, they hurt so bad. I've been an emotional basket case!! (which isn't normal for me...except in early pregnancy) My temp stayed up by 1 to 1.5 degrees higher than my normal everyday temp after ovulation. But today it dropped down to almost as low as it is when I'm waiting to ovulate. I didn't have any of those pregnancy symptoms for a day and 1/2 and then tonight my breast are hurting REALLY bad again and all day I've had sharp pains in my low low tummy.
I had these kind of sharp pains in early pregnancy with both my children, but I'm scared it could be just faint cramps starting up before my period. I'm scared! I'm trying to be patient and know that God is in control and he has my babies birthday already planned. But it's so hard not to worry!!!
Any thoughts?? Anyone in my shoes this month? anyone out there waiting to test?

Also, I have the home pregnancy test that work as early as 9 days after ovulation but in my past 2 pregnancies it took a realy long time to get a positive test! I've even had negative blood work when I was actually pregnant! So... I'm just nervous! and needing to hear from you wonderful ladies! Guess I'll know in the next 4 or 5 days if my period doesn't start!!
Praying it doesn't!

Thanks for reading!!!
