Ok the OB said have sex to try to get labor going and the past two times we’ve done it about 45 minutes after my husband goes inside me I get WICKED cramps from my back to belly and they last for hours. Last night they turned into contractions they lasted about 45 seconds every 4 minutes for about 40 minutes now in the morning they’re gone. Idk if it’s putting me into false labor or the semen is really hurting or if I have an infection or something. Please someone tell me what’s normal?
