Getting pregnant after IUD removal

Kat

So...on the 17th of this month (Jan) my Paraguard fell out at random. (Was planning to get it taken out in April when our first turned 1, but we decided to just try early since it fell out)...I’ve had it in for 6 months at that point and cycle was always on time, around the 26th of every month. Well in December it came a week late on the 3rd, and in Jan it came on the 1st but a week later I basically had another period, I was spotting kinda heavy for what “would” have been my entire fertile window (12-19th). Anyways I had unprotected sex where he finished in me on the 19th, 21st-23rd, 25th and 26th. AF was due on the 28th and...not here. Question is, I am having symptoms different from normal AF. Normal PMS means irritable, eating sweets, tired, and mild bloating. But now I am more weepy than cranky, not hungry and if I am I have to eat small otherwise I’m nauseas/stomachache, suuuuper tired, and SERIOUS bloating/water weight, and weird cramps in lower back or vvvv mild period-like cramps. Boobs are also super sore. My cervix is high and soft (app says before AF it is lower and hard?)...I tested on the 25th (so like 5dpo?) and it was negative. Wondering what the likelihood of me having conceived is this month, or if PMS symptoms changed at all after getting a copper IUD out? Feel free to comment suggestions or anything really, just confused and when Can I even test if i were pregnant?
