What should I do?

Erika
Okay so I recently went to the doctor I did tell him that I'm trying to conceive and my periods are soo irregular so he gave me BC for 3 months I haven't had a period since April 1 they took a test at the doctors and was negative this has been the longest I haven't had it I'm afraid to take the pills and I'm pregnant I haven't took a test yet so idk since its been that long I'm pretty sure it would have been positive when I went to the doctors Any suggestions ?
