I missed my last period. Was supposed to be on the 28th of June. Took like 6 pregnancy tests over the Course of a week and all negative. No other symptoms so I just figured it was from stress. Started taking my ovulation tests on the 7th and got a positive same day. Now I have had spotting yesterday and heavier today. Very confused as I am usually very regular!! Is it implantation or just a super late period!? Help!
