Hi, I am new to using OPKs and started using it after my gynecologist suggestion. We have been trying for a baby since a year now. Last month, the OPk showed positive/ peak only on two days and faint lines were present for a day before and after. I didn't take OPK after those 4 days. This month, I thought of trying since Day 11 pafter my periods and had some faint lines from Day 13 to 15 and positive/peak lines from Day 16 to 20. On day 21, the test was low and had some very faint line. On Day 22, I got a positive test for OPK in the morning and took again in the evening to verify and it was low. I thought it might be the problem with the test strips. I took today and the tests were again positive and it's in peak. I took another one and still it's positive and dark. I am not sure what's going on ? Has anyone experienced this situation before and could share some advice pls. I have 30 to 34 days cycle and there are no other symptoms. I don't have PCOS problem since I read online it could happen for women with pcos. Please suggest. Thanks.
