Cycle Day 22

Still having my sore throat, flu, bad cough, bit of fever, headache and bit of toothache (or shall i say gumache)

Yesterday : cycle day 22
Today : cycle day 23

After i coughed my organs out yesterday i noticed a brown discharge which was too early for a period, too early for an implantation bleeding and too weird to hv it as an ovulation bleeding because i never got this before.

So i googled, most of them said and found out that they were pregnant.

If i recall, yes my previous cycle was from hell. Positive hpt before period and after period.

Then last nigt at around 8.30pm i tested for opk, and it was dark! Not dark enough for a positive but it's almost positive!

This is very confusing.....why do i get a positive opk and spotting on the same day?...why??
