I thought I'd list what appointments I've had so far to give you an idea of what to expect, however it is different depending on where you are, I'm in London.
1 - I went to my GP the day after my bfp, but there was no need for me to go and if I got pregnant again, I wouldn't rush to go really.. But maybe just give them a call and see what they advise (like you said)
The doc just said well done dear and sent me to book an ante-natal appointment for when I was about 8 weeks. lol
2 - When I had that appointment she just went through a few basic's and sent me to the hospital to have the first lot of blood tests.
3 - The next time I saw anyone was my midwife when I was 12 weeks, she goes through alot with you and thats the first main appointment I'd say. I also heard the heart beat at this appointment, first time it all felt real for me !!
4 - Then I had my 12 week scan.
5 - Had to book to see GP at 16 weeks, at this app I listened to heartbeat and had a general check up.
And now my next appointment is my 20 week scan or mid pregnancy scan as they say which is in about 3 weeks, I would have gone past 20 weeks by then!!
So I haven't had many appointments really, 5 so far.. My OH has come to all of the appointments, but he didn't really NEED to be there, so dont worry to much if he cant make it..
