It could be a false positive urine
pregnancy test so repeat it in lab using early morning sample
If that is positive,
There could be 2 scenarios
Either you have not got the desired effect and have conceived despite using the pill.....
Or you have conceived in april....
Sonography can be done to ascertain the pregnancy along with
beta HCG levels...
the pain is mostly due to acidity and can be relieved with antacids
Best option is to meet a gynec and get evaluated by tests
If you are
pregnant and dont want to continue pregnancy the gynec can help you too
