Hi everyone, my husband and I was trying to have a baby for a long time it seems like and we finally had gotten one but we ended up having a miscarriage last year in November at almost 8 weeks in . So at the end of January we started to try again and have not had any luck ... but on the 11th of this month i was supposed to start my cycle and 5didnt start until today ... so at work today i started to feel sick , my body was getting very hot , i was shaking bad , could barely stand for a couple of minutes, was cramping bad , and then i threw up (i haven't thrwn up in over a year , even when I was sick , yes ik thats crazy) . I took an at home test i think last week and it was negative ... Do anyone know what could be going on ?
