???????????????????

I have two periods last month, 4th August for 5 days it stopped on 9th August. Then I started again to bleed heavily again (period again) with blood clots on the 15th August and it stopped on 20th August then I ovulated on the 21st and the 22nd August then on the 29th August I started having this which is so different to all my periods I have. Then last night after having sex with my sexy man we finished and this happened sorry about the brown in the background it's dried blood ages ago. It stopped three days ago. Should I do a pregnancy test and when??
