<s>[INST] I have been ttc for 2 years. My husband has low sperm count and I have PCOS. I am due to come to come on my period in 3 days but feel very different this month. I had been getting lower back pain, sensitive nipples, sharpe stinging pains through my breasts and abdoman and vomiting in the evening....could these be signs of pregancy? [/INST] Hello. Thanks for writing to us. The symptoms that you are having could be related to pregnancy. But the only way to confirm this is by doing a urine test available over the counter once your periods are overdue by a week.I hope this information has been both informative and helpful for you.
