hey everyone. this is my first post in the 1st tri. I just wanted to see if someone could confirm this for me. I have irregular periods and my last was on the 23rd of jan and I had a positive opk on the 16th of feb. I only DTD once and that was on the 14th. my last cycle was 39 days so I'm assuming that's what this one would have been. how many weeks am I? I'm sure I'm about 4 weeks & 1/2 days. is this accurate? just so I know when to book my reassurance scan for. Thanks ladies.
