My periods are really irregular, I can have one, one month and not the next. The last period I had was July 21st which lasted around 4 days as normal, I haven't been sexually active since nov last year until august the 30th since then I have been engaging in intercourse. Around the 26th of august my boobs started to hurt, this is normal a couple weeks before I am due on so I knew I was expecting Mother Nature, now the 6th November and I still haven't had a period but madly my boobs are still sore, not sore as to knocking them slightly and they are throbbing if I squeeze I can feel the pain some days they do get more sensitive but nothing major. Having sore breasts for what 3 months is a lil worrying, my partner had the snip many years ago so we didn't use contraception. I thought could I be pregnant but all 8-10 tests have been negative, being cheap tests 5 pound for 5 or 2 for 2 pound that kinda thing. I was wondering what you thinking. I have had cramps within the 3 months so I thought I would be due on any time now but that never happened. I'm just confused as to what is going on.
