Hi all, sorry for my long story but want help from you all.

I am 32 yr old & started ttc for #1 last month. my first day of last period was 26th march. I think I ovulated between 6-8April as opk showed LH surge on 6th. From 9th April my body started showing weird symptoms. I am usually warm in the nights but my husband complaint that I am super hot throughout the day whenever he touches or hugs me.Since 12th I started having mild cramps and back aches and also hot flashes for 15-20 in my feet every night. And since 14th my breast were slightly tender and have been feeling nausea briefly couple of times in a day but not that I cant tolerate it. And on 16th I had a little diluted pink spot only when I rubbed with tissue and next day it became little brown and it stoped. Next day which is yesterday I woke up with severe migraine and follwed by right pelvic pain and cramps throughout the day. My breast and nipples are also very tender to touch suddenly from yesterday in comparison to last few days. I can see little red veins in one of my breast and the color of my nipples seems to be darker than usual. My husband confirmed these things so was relieved that my eyes have not gone bad. I did pregnancy test today after 4-5 hours of waking up but got BFN. Not sure if it was late for the day or I am testing it too early as I am 25 days past my lmp.

Did anyone else had this experience or is it just my pms or just my mind playing up with me?
