Hey,
While anal sex without a condom can impregnate you, the chances are much more slim since the sperm would have to travel from the anus into the vagina and then up to the uterus (that's a lot of swimming!) Plus, his ejaculation was not inside of you anyways, so the only sperm that could have travelled would be pre-ejactulation, which contains significantly less sperm than a full ejaculation. Buying a more expensive test (if it's an option), might put your mind at ease, but if you are seeing a doctor anyways, perhaps he/she could run a more accurate one for you.

Your late period seems sort of normal, no? You said yourself, "my periods are usually irregular" and that you "have been under a lot of stress lately and my sleeping schedule has changed in the past month." Both of these indicate that not having your period yet is totally normal for you. Your body schedule is changing a lot, and with the added stress, anyone could have missed a period.

You're other physical symptoms might be from something else- the abdomen pain seems pretty serious and I would definitely have that checked out (as you are doing so). Heartburn can occur for many reasons unrelated to pregnancy as well. I do think you should mention all of these things to your doctor though so you can get treated properly.

To be honest, from what you've said, I doubt you are in fact pregnant- but even if you DO test positive, there are many options! No need to worry or stress yourself out even more. Everything will work out

Take care,
