Okay a bit of a back story...

I had a child in 2008 and then had pcos and had fertility issues for 10 years.. Got pregnant with letrozole last march and had a second child in november this last year.. Anyway...

After her birth i started my first post partum period in January and since then my cycles were about 33 days I am not on birth control other than condoms. We had a oops in may and since I have not had a period. I took several pregnancy tests the week of missed period and all were negative..

After having pcos before and fertility issues inwonder of I am just beginning infertile again or maybe retest for another pregnancy (I hate to do so it messes with my head)

I have been having some symptoms but they are also pms related. I get cramps like I should start my period off and on and it never shows along with sensitive breasts.

Does anyone have similar experiences or advice I would greatly appreciate it. Thank you.
