Hello. I just recently found out i'm pregnant again. According to my last period i'd be 7 weeks. I had spotting for about 4 days the week my period was due (3 weeks ago) which i did assume was implantation bleeding. I took a pregnancy test the day of my period and it was negative and then took 2 more tests throughout that week and both negative (digital ones and line ones). I assumed i wasn't pregnant but tested again this week and the line was faint but there. I've started having very vague symptoms such as nausea but not severe at all like my last pregnancies and i took a digital test yesterday which says 1-2 weeks. This would mean i'd be around 3-4 weeks pregnant but how would that add up with the implantation bleeding/last period/etc? I usually ovulate around the same sort of time so the dates don't add up. Is this cause for concern or is it just possible for the dates to be THAT out?
