Hi. My cycles for recent 3 months are, 28, 26 and 27. I had a regular cycle before. With my recent, I had unprotected sex from day 13 to 16 then on day 19 and 20 I had what I think is implantation bleeding which I have never had before accompanied by cramps, lower back pains, nuasea, feeling pukey, sensitive nipples, tingling feeling in uterus when peeing, tender breast and excessive sleeping. Everything got worse on day 26 then On day 27 my breast was very sore and I later got my period. Dat 28 I have heavy flow with clots and unbearable cramps. Any chance of being pregnant? 😔 I am scared of buying a test because of dissapointment. This is my 4th try.
