I am 22 and have been having unprotected sex with my boyfriend for about a month now however, I do take my birth control (Lo Loestrin Fe) perfectly. I have been experiencing regular constipation, gassiness, abdominal cramps and a heavy sensation above my rectum for about a month now and often times it is most severe soon after having sex. I don’t think that pregnancy is likely but I also have not had a period in over a year due to my birth control, so I wouldn’t know if I’ve had a missed period. What could be causing this and should I be concerned? I have been reading around and have seen people mention the possibility of endometriosis (my mother has had a history of endometriosis) or the possibility of a tipped uterus. I have an appointment with my obgyn in about a month and a half and my insurance won’t cover an earlier visit. Would it be ill-advised to wait this long to see a health professional?
