Is it weird or possible?

My hubby and I have been TTC and it has been over 2yrs and I want to know if anyone ever felt like this before testing. ok. it has been a while TTC and this week i do not know if it is intuition or is in my head. But lately i have been feeling like to take care of myself more as far as eating properly and not missing meals. and i was taking vitamins (fish oil and folic acid) those are good for pregnancy but has a label stating if you are pregnant consult your Dr. first and the other day i went to take one and it did not feel right to take it. when i squat, i will do so now in a fashion that would not harm my uterus if i was preggo. these are things that i usually do on daily the wrong and all of the sudden i have this strong feeling to do it differently. sorry for being so long i just wanted to know if anyone felt that before finding out they were pregnant. My last AF was 122709. i have no other symptoms instead of being really tired and eating more maybe. i am big time irregular so i did not think of anything when i did not have my AF in jan or feb. Please Please do not tell me the obvious about taking a pregnancy test. I wanted to know if anyone had motherly instinct before getting a BFP or is it in the head? Thank you in advance for reading and answering the question above only please.
