Could I possibly be pregnant?

[Angifi]

Hello, I am new here. I'm 42, have a 9 month old darling son,Charlie.He is still breastfeeding whenever he wants and I haven't yet had a period.
I'm thinking there's a possibility I might have conceived last weekend, as I haven't yet ovulated, but noticed fertile C.M the day after we bd for the first time in ages.Of course thaat could have been residule semen(?it looked at felt like CM - very stretchy and clear).
Anyway I have started to notice that my bbs are tender (and never have been with b.feeding), I have a metallic taste in my mouth, and the smell of eggs cooking this morning was yucky.
I dunno, seems so unlikely(I know my fertility must be wanning at this age), yet it is possible.
Anyone else had a similar experience?

Thanks Angifi. It's so confusing when your body sends out this messages like this isn't it? Maybe you both need to revisit the issue if you're both in opposing directions? Good luck and have fun with Charlie.
