Side Ache & Menstrual Cramping

[BEM1984]

My husband and I have been TTC our first baby for 4 months now. I had an IUD for 4.5 years and didn't get a period for 4 of those years. When I had it removed it took me 31 days to get my first period. I've been tracking it ever since and they seem to come every 25 days on the dot but that could just be a fluke since I don't have much info to go on. I am due for my period in two days. I've been having weird side ache like cramps for the last 4 or 5 days. It seems to switch from my left side to my right but sporadically throughout the day. I've also felt mild cramping in my lower abdomen right in the middle. They feel different from normal menstrual cramps though. Is this is sign of pregnancy? I took a preg test 2 days ago and it was negative. I'm sure its too soon to tell but has anyone else experienced cramps like this?

I didn't have cramps exactly like that, but I did have mild cramping. Women usually ovulate about 14 days before their next period and it takes anywhere from 6-12 days for implantation to happen, and another 2-4 days for the HCG to be high enough to show positive on a test. So wait at least until your period is due to test again.
