so done feeling sick!

(sorry it's kinda long) so, i didnt track ovulation with anything other than my apps. according to them, i ovulated between oct 4-6 depending which app you look at. so going off that im 9-11 dpo today. well last monday, 3-5 dpo i started feeling yucky. tuesday woke up with diarrhea, and really strong waves of nausea that had me feeling like i was gunna puke up all my insides, but never puked. Wednesday i woke up with a migraine that had me bed bound most of the day, with a bit of nausea mixed in. thursday i woke up feeling good enough to go to work but still had a headache, tummy cramps, and could feel a cold coming on. friday the cold symptoms got even worse. yesterday (saturday) i had a full out cold but it didnt stop me from doing my normal daily things with my 2.5 yr old step son. but my tummy still felt pretty yucky. nothing major, just slight cramps and a bit of an upset tummy. today (sunday), still have the stuffy nose, cough, and the nausea has come back. along with a bit stronger cramps. we were walking thru walmart and i had to stop three times because i seriously felt like i was about to throw up. i also peed about 3 times in 1.5 hours. so my fiance decided we could buy a frer, when we usually use dollar store cheapies but he said "this time we can get a good one" af is not due till about thursday-saturday (no later than saturday but it always has a 3 day span.) and usually a week before af i get sore boobs. but they feel fine right now, no soreness. i should also add i got my tubes opened up on cd5 this cycle. and ive heard you're apparently more fertile after you get that done? i dont wanna wait that long to take the test. and if this isnt pregnancy symptoms, then i just wanna be better already! im so done with being sick and feeling like crap. itd be nice to actually either feel okay, or have a reason my immune system seems to have gone to complete shit.
