Hi Anna, we have a TTC and beastfeeding buddies group here if you want to chat to other women about it.
I got pregnant while I was breastfeeding. Once my period returned I started charting and I wasup the duff in no time .
If you're not chating one of the easiest ways to spot if you're fetile is checking your cervical mucus. There is an article about it here. If you see any that looks like egg white tell your DH not to stay late at work...
