I had been on bc pills for about 14 years to help regulate my period. I stopped taking the pill in October and started taking pre natal vitamins because my husband and I were going to start trying to conceive this month. After being off the pill I only got my period in Nov and nothing since then. We have now started trying to get pregnant and I bought cvs ovulation strips. I started them Monday and coincidentally it was positive both in the morning and evening. Tuesday it was positive in the morning and midday and negative in the evening. Today it’s been positive morning and midday. I just got home from work and took another test and it was negative. I’m just confused. Don’t know if I should just buy the digital ones. I’ve also read that you can get false negatives on opk’s so I’m not sure what to do.
