Dairymps - I am so sorry about your SIL. I can totally understand why you feel guilty as she has kids and you don't. And it makes it worse that you were both pregnant at the same time. DH's cousin (who I am very close to) miscarried 6 months ago (she has no kids). She had been TTC for ages. She has been TTC again for the last few months (and has been keeping me informed, which I find difficult). I already have a 2.5 year old DS, and here I am pregnant again. I feel very guilty and I am dreading telling her and don't know how to go about it. So I totally understand what you are feeling. But it's not your fault, and you (we!) shouldn't feel guilty, although I know that's hard.
I have only tested once. I tested loads of times in my first pregnancy though! I really enjoyed it! Although once I didn't get a line, so I panicked! This time round the CB test said 3+ weeks, and I still haven't had a period and have sore boobs so I think I am pregnant. Might do another test next week at my Mum's house.
Only DH and I know just now. I am visiting my Mum next week so will tell her then (as feeling increasingly nauseous, tired etc. and drinking decaf tea so she'll know). Won't tell DH's family until after 12 weeks as SIL (DH's brother's wife) is pregnant with their first and is due soon, so I don't want to steal thunder/impact on the new baby etc.
Seriously - I love piping hot baths too, so I share your pain in missing out! I also drink tea continuously so I have switched to decaf (Twinings do a good everyday decaf which is nice). I am also drinking peppermint tea and have bought some Ginger tea to try to help with the nausea. I also sucked ice-lollies (plain kids fruit ones) all the time last pregnancy to help with nausea which worked a treat.
