so it’s been three months that i’ve had sex. that month that i thought i was pregnant bc we used an ultra thin condom my period came 5 days late but it was with someone clumps and really harsh cramps. but the days were lighter except one which a bunch of blood came out. the next month after that it came on time and it was more clumps and blood but the same bad cramps. i’m two days late now. should i be worried? i also took 4 different tests before i was late this month and they were all negative.
