So this morning starts my 'fertile window' so I took an ovulation test and it was positive. Yesterday evening I had a tiny bit of red blood that turned into brown and only was there when I wiped and lasted for only a couple of hours. I also took two pregnancy tests this morning at the same time and they were positive too. But last week I had what I thought was a full blown period that lasted from 12/21-12/25. It was heavy at times and cramping. In August I had a early miscarriage and so I want this more than anything. Can you have a period and be pregnant the next week? Do you guys think this is truly a positive? Has this ever happened to you? Thank you so much in advance!
