TTC, weird symptoms, what the hell

I'm going out of my frickin mind here. I'm 34, panicking about never having kids. Husband and I are trying but probably not as hard as we should be.

Had sex on confirmed ovulation this cycle, and everything else was normal.

Then i started having out-of-the-norm shit happen. For instance, a very sudden affinity for oranges and orange juice. I haven't been able to drink orange juice for years because it used to make me sick.

On Sunday (6 days before my period was about to start), I had extremely light brown spotting. Now, my periods are very regular. Almost like clockwork, and they never, ever start out with very light brown spotting. On Monday, it was very, very light period-like bleeding. Also out of the norm.. but it morphed into a medium period that was very watery Monday night. My periods are never watery. Tuesday was also a bit watery and a bit lighter.

Headed into Wednesday and im getting the "end of period" very light barely there bleeding.

None of this is normal for me. Im also unable to sleep, its 6am where I'm at right now and I fell asleep after work and woke up at 2:15am. And for no reason, I started feeling insanely overwhelmed and had to stop myself from sobbing so I wouldn't wake my husband.

What. The. Hell is going on? Either this is heavier than normal IB, or im just on my period and its weird.. but I feel like everything is out of control.

Thoughts? Anyone else every experience this? I may take a test tomorrow just to put it out of my head either way.

Ugh. Im tired and clearly losing my shit.
