Yeah, the confusing thing is that pregnancy and the witch seems to have the same symptoms, even down to throwing up in the morning. It is so all consuming that it is really hard to try not to nit pick every little thing but it does drive you crazy. Exactly why I started looking for forum, I have never been on one before but thought it would be great to connect with others who are going through the same thing.
Def recommend the clearblue digital opk, it takes the guess work out of it, it will be interesting to see how you go using them for the first time. With my boy it wasnt till after I got a BFP that I realised the opk was positve on the day I 'thought' it might be, although that was at the start of my baby making journey. Thats why I decided to go straight for the digital ones for my daughter, but they are really expensive here (in New Zealand) about $65-70 US$ for 7 tests so its quite an investment! Luckily it worked first time with her so only had to fork out once.
Really looking forward to the big O this month but its still at least 10 days away so enjoying a couple of wines and some sushi till then! Good luck everyone!
