I found out I'm pregnant on Monday but the thing is I'm clueless as to how far along I am because I have no idea when my last period was, only that it was roughly about 2 months ago? With my last baby I tracked my periods and ovulation to the day so I knew exactly how far on I am but how does it work this time around, like when do I phone the midwife? Will they have to send me for an early scan to determine how far on I am?
