Yay am on computer so can write sensible size message!!
Congratulations Artichokes! My dd is 19mo too, how exciting!
Well I went for blood test today but thought no, I'm putting my foot down I want a scan after freaking out last night so I went to EPU and spoke to a very nice doc who organised an internal scan for me there and then!
And....theres a little tiny beany in my womb just where it should be!! Yay! 
I went for bloods after as it was so early they couldn't see a heartbeat but the scan lady agreed with my dates which makes me 5 weeks today....which has also put my mind at rest about the lack of symptoms coz I know they didn't start until about 6-7 weeks last time. Going to get results of blood test tomorrow which will tell me if bhcg is doubled as should be but the scan lady said everything seemed as it should so once I've got blood test results tomorrow I think I'll be much more relaxed.
They think the reason for the pain is that there is a small patch of blood which she said is really far away from the bean so not to worry about but that it looks like it came from the burst cyst on my right ovary. She was saying something like thats how the egg is released from a burst cyst but sometimes it can bleed a little and that can cause a bit of pain. As it was on my right ovary and thats where the pain is I guess that must be it.
Sorry for the ramble...feeling sooo much better! Just looking forward to blood test results tomorrow to confirm it really.
Hope everyones ok today!xx
