Weird month?? Period? Pregnant? Ugh!

So here’s what’s going on. First month using OPK and BBT but been TTC for a year.

At 8 and 9 dpo I had super super super light brown spotting, then at 10dpo it was heavier but still light, 11dpo it seemed like it was def a period starting, 12dpo back to light and now I’m 13dpo and its gone.

My temp dropped on 10dpo but went up a little on 12dpo and spiked a lot today (however I think I’m sick too- sore throat and cold like symptoms).

So... now my “period” is done before it was even due (technically was due tomorrow). I normally have a 6-7 day period with day 1-2 being super heavy and cramps that require medication. I didn’t have any period cramps and didn’t need any medication.

Any thoughts? I did take tests on 8,9,10dpo and then this morning at 13dpo, all negative- but only stopped bleeding last night.

Chalk it up to just a weird period month? What are your thoughts/experiences? Thanks!
