Ovulation help

Cam someone help me with ovulation tracking?

I am only using strips, no thermometer yet since this is my 2nd month ttc. I got a darker colored line over the weekend, but it wasn't dark or darker than the control line. And now it seems to be lighter again.

Any advice?

What are some ovulation symptoms?

Today, I feel like I've been run over by a truck, super tired, emotional, stressed, boobs are sore, acne and a massive headache with a lot of water discharge.
