No reason and slight cramps on and off on each side but not both sides at same time. Ill wait a few days like someone said to wait a week to see if I get my period or any kind of bleeding then test for pregnancy but I'm going in the clinic to get it done I trust blood work and stuff vs a pee test because in case you're never fully know if it's not effective because i know lots of people who had a period and a negative test while pregnant. But if not I still am going to the doctor just to get a regular check up besides the question about pregnancy because I am sick of others asking if I'm pregnant and saying I look like I'm getting more pregnant and I don't know lol but I do know is I have been eating more than I usually do usual it's certain balance diet I'm on but been more hungry and gained a few pounds before I moved in with him I was in size 0-1 now 3-4s so slightly more pounds then before. Better safe than not knowing what is going on :)
