Hi! 6 months ago I had unprotected sex. I took the pill next morning and had next month period( my periods are irregular). For some reason I got scarred at some point that I might be pregnant because I had pains in my lower ab. I must say that I've been wearing at that time some jeans that made me look skinny and they were really tight and mot so uncomfortable. I got scarred that I might be pregnant and done literally 10 pregnancy tests (all different brands) which were negative. I got over the two months my period which was a bit reduced quantitatively than it used to be, so I went for an ultrasound ( I would've been 2 months pregnant at that time). The radiologist told me I'm not pregnant, however I wasn't and I am still not comfortable with myself. I feel like some fluttering in my pelvis and also a lot of gas in my intestines. I am not sure what to think anymore.... can I be pregnant ? or it's something stress related ? I've been in a lot of stress lately and I can even see my aortic pulsing and also feel it when I put my hand above my belly button. I also have muscular spasms sometimes. That's probably because I got used for some reasons to keep my ab strained. So, the question is if I can be pregnant ? I feel like I'm getting crazy....
