Hello, We've been trying to conceive. I usually have a 28 - 30 day cycle. I experienced cramps on night approx 12 dpo then the next morning I started what I thought was my af (bright red blood) it was a very light flow compared to what I usually experience but I needed a tampon, the next morning I used a tampon but by the afternoon it had tapered off to a very light flow and in the afternoon was just when I wiped. For next last two days I have just had slight brown spotting just when I wipe. I have done a hpt but it's negative. Could i still be pregnant despite the negative? Unusually get very heavy periods so this is very unusual for me. I am 37. Also I want to ttc this month and planned on starting epo as it helped me conceive last time but I am unsure now in case this bleed was implantation or I am pregnant and your not meant to take epo. Really appreciate your advice as very confused! :( Thank you
