My partner and I had oral sex on the 30th of March. As it was our first time, we got worried and I took an I-pill (1.5 mg Levonorgestrel). That month, I got my periods two days late on 11th April. After this, we again has oral sex on 8th May, which is four days before my supposed period. This time we had a feeling that some semen may have reached my vagina, although it is unlikely, as we were safe. But still worried, I took one Unwanted 72 (1.5 mg Levonorgestrel). Now, it is 13th May, and I still haven't got my period. I did have mild breast tenderness, diarrhea, and slight abdominal pain like in periods. This is still going on but i am not bleeding. I am two days late as of now, should I be worried? We didn't have sex, just oral and at one time we did penetrate but withdrew due to pain. But the timing was four days before my periods, so isn't it unlikely that I get pregnant? Did the i pill change my ovulation date? Is it bad that I used two different pills for each time?
Also, if I do bleed now, is it the withdrawal bleeding or my periods? If it is withdrawal blood, does it mean I am definitely not pregnant, or am I still in the woods? Should I take a test? I know there are many questions here... but I am very worried, we don't have the capability to be pregnant right now... please help.
