Hi my lower abdomen feels tickly and am getting a pulling sensation inside. My partner and I have had unprotected sex at the end of my ovulation cycle, and have never experienced anything quite like the fluttering. I thought I was going crazy after taking a test with a negative result, but am not due a period until next week. Can you suggest a next step or if you ve heard this before, as people keep saying a week is too early for symptoms. Thank you
