what do you think??

So dh and I bd the last 2 nights and it feels so different. Is this a good sign? It's almost like I've spent the last 6 months doing kegals. Either his manly hood is growing or my lady spot has gotten tighter. Still experiencing bouts of breast tenderness, naseous, tiredness and lower back pain that comes and goes. I'm 8 dpo today but I'm thinking I'm going to wait until Monday to test.
