Okay so I had my "period" last week but it was super short in comparison to normal. I have a paragaurd iud and my periods are normally heavy and about 5-6 days long my last one was light for the first day and then about a medium flow then back to light the second and third day after that nothing. So it was only three days long. This week I get nauseous in the evening I'm exhausted most the time and now today I started a moderate cramp kinda like my period cramps which I not normal for me except before my period about a day before. Idk what's going on and I was wondering if anyone could give me advice or have experienced this before. Please let me know I'm wondering if I could possibly be pregnant with the iud
