Regular periods and ttc at 41

Lyssa

My boyfriend and I been trying for several months.

He is 10 years younger than I am.

I already have two teens.

Every month is like a rollercoaster, I feel tired, emotional and hopeless.

This cycle, Ive had light spotting , one Brown and then à pinkish/red after two sexual relations .

I have never had this before, should I be worried? I've had spotting one day or 2 before my period but not more.

On the Internet, some say cancer and then others argue it might be implantation bleeding.

Im confused.

I tried a pregnancy test 6 days sonner and was negative today at day 21. I have 26 day cycles.

Thanks for reading,

Lyssa
