Hi My period had been unusually odorless and very light. It was dark red with brown streaks sometimes light red and only slightly flow when i used the toilet. Only lasted for about 3 days. I had unprotected sex about 11 days after the start of my last period. Bleeding started 3 days before expected period. i thought the bleeding was my period because i had sore breast as usual which vanished since the bleeding stopped! i was getting mild cramps and a few painful ones that disappeared within few seconds. it is now day 6 since i first saw the bleed. Could that have been implantation bleed and could i be pregnant? My lower abdomen feels slightly sore in the centre and i have been burping more than normal but not too much. I have been ttc for a while now and this would be my first pregnancy (hopefully). i am in mid 30s!( scary) Oh, pregnancy tests every other day shows negative. Been using the alere brands. Any chance i could be on the way to glory?
