How many weeks am I?

Miriam

Not sure where to ask this question...

I have irregular period due to pcos and did not have a period for a while, however I got a positive ovulation test on may, 16 and had intercourse. On may, 26 I get a positive pregnancy test. Is there a way to calculate how far along am I? My doc appointment is not in another 2 weeks. Tnx for the help!
