I’m on day 45 of my cycle. The last pregnancy test I took was Saturday and it was negative. Today I feel crappy. I woke up with a fever of 100.8 and have thrown up a few times. I also feel weak, and sluggish. I have a real bad headache. It almost feels like a migraine. My back is hurting really bad. I also have slight cramping, and sore/tingly boobs. I’m wondering if I’m pregnant or if I’m coming down with something. When should I retest? My longest cycle was 47 days. Should I wait till then or take one now? Has anyone felt like this and ended up being pregnant?
