Am I going crazy? Please help!

I need someone to put my mind at ease because I feel insane.

I’m 6 months postpartum and still breastfeeding. I’ve had 2 periods since having my baby but I haven’t had one for like 3 months. I haven’t tracked when my husband and I have been doin the deed, but we do use condoms when we do BUT, honestly, I leave all that up to him… so I don’t know how “perfectly” we’re using them.

This last week has been so weird. I started feeling nauseated last Tuesday so I tested. Negative. For several more days I continued to have waves of nausea, dizziness, irritability, mood swings (seriously annoyed one minute and perfectly happy the next), cramps, increased appetite, increased thirst, and LOTS of cm. I tested again on Sunday and it was negative.

I know that all this could be (probably is) my body trying to have a period. So many of these symptoms are just so strange, I’ve only experienced some of them during pregnancy. Both times I tested were with cheapies from Walmart. Should I wait a few days and test again, or accept that it IS negative? I feel like I’m going insane.
