Something needs to give

Unknown

My last period was 10/07 i came on 11/19-11/20 but they was super light and pinkish, not like a period. I’m pretty sure it was implantation bleeding. I took a pregnancy text 4x and they were all negative. I have every sign of pregnancy doe. Cravings, loss of appetite to certain foods, tiredness, nausea, constipation , headache etc. have this every happened to any one.
