My ovulation tests have been getting darker and darker. Yesterday and today I had the darkest test lines. I had light bleeding today, and it hasn’t turned into a full-blown period either.
Here are the facts:
1. My periods are normally 25 days long. Tomorrow will be day 25!
2. However, my cycle was 35 days last month (I had been really sick, and was taking cortisone and antibiotics).
3. I have been taking ovulation tests from day 8 of my cycle with extra light lines.
4. We have been TTC every other day since day 8, then every day for the past 4 days.
5. I had very sticky, but very liquidy mucus, increasing from day 20-present, as well as increased “libido”.
6. My lower back hurt bad today. and I had bright red, but very light bleeding, but am not bleeding anymore…just mucus.
7. I had a fever last night (100).
Is there some phenomenon that causes an increasingly darker line on an ovulation test as a woman nears her period?
