Nearing the end of a 2ww

Im currently day 25 of my cycle, and pretty sure I o'd on day 15. Which puts me at 10 dpo.... I only realised a couple of days ago. Back around day 15 when I was certain that I was going to o sometime soon, I came out of the bathroom and announced to my husband " well if you want another child anytime soon you might want to do me today". Well he needed no further encouragement and as soon as the bub was in her cot he proceeded to business! He is very keen for the second. I am still a bit uncertain and fearful. Today I am fighting a sore throat and cough, and as the day has progressed I have been developing worsening nausea. Already Im paranoid and looking for pregnancy signs, trying not to grab my breasts in public! Sore nipples was always one of my earliest signs that I was pregnant. I don't know when I'll do a test. On a side note.......People seem to comment quite freely about the prospect of me having a second bub. Just this afternoon I was at the pharmacy buying formula and the assistant, after chatting to bub, cheerily bade me goodbye and "good luck with the second one". What's with that????? How does she know that this one is my only bub anyway????? Do I look pregnant already? (well I have been gaining some weight lately but that's more related to the crap I've been putting in my mouth!) Anyway.... Time will tell. I'll know this time next week I suppose!
