Me and my partner had sex five days before ovulation and then on ovulation night we had sex twice and he came inside me all three times and then I got my period on the 20th & we had sex that morning and he came inside me again but now it's the 23rd and my period is been on and off like no blood at all! And then just a like a medium amount (nothing like my normal) but I have seen blood clumps so that means I can't be pregnant right? Idk this is totally different and not my period always been 9 days not 4!
