Hello everyone, hope everyone's well. I was after a bit of advice please. Me & BF started talking about ttc this year I'm 31 and he's 33 so at new year thought we'd dtd and give it a go. I've never been totally on top of the length of my cycles but know they usually come around the 15-17th of the month whatever that means! Last months was 15th and no AF this month. I've been having some mild cramps but no blood which has never happened before. I've also been totally stuffed up in the nose (no idea if this is relevant or not but I have no cold ?!) and super sore nipples at night time. I'm really confused if it's signs of AF late or something else so I did s boots test a week ago which came up as negative in the left box but invalid in the right hand side control panel. I just put it down to AF probably being on its way but still no sign. Has anyone else been in the boat before? Now I am stressing out that I have irregular periods just as we are ttc. Help!
