General Help

Hey ladies. I need advice! My period is a week late. I tested 4 days into what my period was supposed to be, and it came back negative. I have had some what of a stomach bug, causing me to be nauseous and throw up a lot. I don’t know if I should keep testing or if my period didn’t come this month due to the bug? I usually get cramping the day before I start and my boobs start to itch. It’s weird, I know but neither of those things have happened yet. I’ve had two chemical miscarriages and we’ve been trying for ten months now. In September I had an ovarian cyst, but have been seeing my GYN and everything has cleared up. My GYN also checked my hormone levels and everything came back within normal ranges. I’m 20, and my boyfriend is 39. He said the next step would be getting a semen analysis done on him to check how his swimmers are doing. Any advice on what I should do now? Keep testing or wait?
