My name is Heidi and this is our 3rd month trying for this pregnancy. Although it's our first month tracking everything not just some things(bbt, ferning, OPKs, cervical position, cervical mucus etc.) my cycle varies slightly but has been between 27-30 days since I weaned. We also have a 2 year old daughter and had a stillborn daughter prior. I haven't had a temp spike so I actually don't expect my period on the 28th I'm thinking the first since I've had 3 days in a row of positive OPKs and am guessing today was O day.
