I have been using the Patch for 3-4 years. Lately I have become inconsistent and change my patch days later than normal. I had my period, although it wasn't as heavy as it normally can be. Prior to my period and even now after the period, I noticed my breasts felt bigger and were a little tender. Sometimes, I get this sick feeling and feel all hot. Also I have had this gush of mucus discharge happen to me twice the past two days. Some other different things I've been feeling is that my hands are shaking a lot and I just had my period a couple days ago, yet I am still having menstrual-like cramps.
So my question is, with all these things I've been feeling and the factor that I was inconsistent in changing my patch, yet I have had my period, is it possible I am pregnant?
Could the body be so used to the patch, that even though it could be pregnant it still carries on normal functionality?
