Hey ladies. I’m a little worried but idk. My last period was November 16th an lasted 5 total days. I happen to be peeing a lot, feeling a bit nauseous, and keep getting these headaches which is unusual for me. I feel like if I was pregnant it would be too early to have any symptoms anyway. And if I’m not what could be causing these feelings? I don’t have a UTI, I’ve had many due to having weak kidneys and I can tell when I have one. i don’t have stds and get tested every 6 months. I’m not very sluggish and tired but not super energized either. I don’t drink lots of caffeine. My period is due in about 4 days. My cycles are irregular and most of the time glow isn’t correct about when I ovulate. I did have unprotected sex many times throughout the past few months and my SO came in me every time. I’m also not sure if it happened while I was ovulating (as I’m not trying but not preventing). My SO has a high sex drive which I don’t mind, so we baby dance quite often. I’ve only been awake for 2 hours and I’ve taken a trip to the bathroom 3 times. I’m not over drinking, I don’t even drink the recommended amount of water each day. I know your all going to tell me to take a test if I miss my period and I will. But I just wanted to see if anyone had a similar situation and if it was pregnancy or something else. Thank you In advance
