I am a 30 yr old mother of 2. For the last couple/few days I have been having contraction like pain in my lower left pelvic region and just yesterday they woke me up around 4 am and I had began to vomit. Im tired and could sleep all day if you let me. My cycle was late this month, by 4 days, and usually last strong for 3 days and mild to light the last 2 days, however this month it came on very light with little to no cramps, (which is never the case with mine, they usually put me down for the first 2 days of my cycle). Anywho, AF came on Friday @ around 430 pm and was very light through late Satruday afternoon, then Late Saturday evening Sunday morning it was very heavy. Then by Sunday afternoon it was almost off completely. Monday no sign of any bleeding whatsoever. Now, My breast arent what I would call tender/sore but if touched they sting a little bit and my lower back is very sore/tense . I know that I cannot be pregnant because of the Tubal ligation that was done 8 yrs ago after the birth of my last child (99.5% birth control), but I know that something isnt right and its cause for concern because if something is going on in there, I def would like to know.
